Let's see the Syntax Substr (source_string, start_pos, Substr_length) As we can see SQL substr function takes 3 parameters. First one is Source string from which you want to extract the segment. Second parameter is Starting position for sub string from the Source string. And the third parameter is Substr_length which is the length for the substring. First two parameters are mandatory to specify while third one is optional. So we can say. SQL Substr function will return a sub string of a specified length from the source string beginning at a given position. First parameter source string can be of any data type CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB whereas both start_pos, Substr_length parameters must be number data type. The returning result of SQL Substr function is of same data type of source string. Let's see an example of SQL Substr function. SELECT substr('www.RebellionRider.com',5,14) FROM dual; Here in this query url of my website www.RebellionRider.com is our source string with the total length of 22 characters, Now, I want to extract the name of my website that is, RebellionRider. So if you count the total length of the name of the website, it is 14. That's why I have specified 14 as my third parameter of SQL Substr function which is substr_length. Also the name of the website RebellionRider is starting from 5th position therefore I have specified 5 at second parameter of SQL substr function which is strt_pos or starting position. Execute it. Here is our result RebellionRider When starting position is larger than the length of source string. In this case SQL Substr function will return NULL as a result. Let's do an example. SELECT substr('www.RebellionRider.com',23,14) FROM dual; As you can see here I have specified 23 at starting position and the total length of our source string is 22 characters Let's execute And the result is Null. Second scenario When the Substr_length is greater than source string In this case the segment return is the substring from starting position to the end of the string. For example SELECT substr('www.RebellionRider.com',5,23) FROM dual; Our starting position is at 5 means at the first R of RebellionRider and length of substring is set to 23 which is greater than the length of source string that is 22. Execute. As you can see we get a substring from first R of RebellionRider till the end of the source String. Third scenario When you supply numeric or arithmetic expression or a DATE instead of character as Source string to SQL Substr function In this scenario If you have supplied a numeric string instead of character as source string, the oracle engine casts them as a character when they occur as parameter to SQL Substr function. And if you have supplied Arithmetic expression or a DATE then The Oracle engine first solves or evaluates the Arithmetic expression or the DATE Then casts them as a character. Means if you have arithmetic expression in your source string then oracle will first solve it and then change or say cast the value of its result into character. Let's see some example. SELECT substr(50000-7,2,4) FROM dual; Oracle first evaluates the arithmetic expression that is 50000-7 equals to 49993. And then oracle engine casts this result 49993 into a character string. Means 49993 will be a 5 characters string. Starting position of substring is 2, that means from the first 9 of 49993 We specified the length of substring is 4 so we must get 9993 as our result. Let's check execute

PL/SQL: Without using Length function
 
06:22
In this tutorial, you'll learn how to get the length of a string PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.

Oracle SQL Tutorial 26 - UTF-8 and UTF-16
 
05:46
UTF-8 and UTF-16 are different encodings for the Unicode character set. Let's discuss UTF-8 first. UTF-8 is what is known as a variable-length character set. This means that the amount of storage a character takes up depends on what character it is. For example, if we store the character A, it will only take up one byte. In fact, ASCII is a subset of UTF-8. That means UTF-8 encoding can work with ASCII data. If you are new to computer storage, a byte is a very small amount of information. The smallest thing a computer can store is a bit. 1 or 0. On or off. There are 8 bits in a byte, 1024 bytes in a kilobyte, 1024 kilobytes in a megabyte, 1024 megabytes in a gigabyte, and 1024 gigabytes in a terabyte, and 1024 terabytes in a petabyte. Considering it is completely possible for a database to be multiple petabytes, you can understand that a byte is very small. If you store a non-English character, the size of UTF-8 will increase to 2, 3, or 4 bytes. If you think back to when we used the VARCHAR data type, we passed in 50 CHAR. The reason we throw in that CHAR is that the default for Oracle is 50 characters. Now you can understand why adding the CHAR might be important. If a character can take up multiple bytes, you cannot guarantee 50 characters. Now, on to UTF-16. UTF-16 is also a variable length encoding, but it differs in that It is either 2 or 4 bytes. That means to store an A, it now takes two bytes rather than one. Even though a byte is so small, when you are storing billions of characters, an unnecessary byte really adds up to a lot of wasted storage. We can only represent so many characters with 2 bytes. When we run out of options, we move to four bytes to allow for other characters. Which do we use? It often depends on what platform you are on and also what languages you are working with. For example, if you are working with Asian language, UTF-16 stores each character in 2 bytes while UTF-8 stores each character in 3 bytes. So you could save space by using UTF-16. Additionally, UTF-16 works better when you are writing code in Java or something from Microsoft .NET because UTF-16, or a subset of it called UCS-2, is widely adopted. Other than that, UTF-8 will be the one you want. Now that we have built a pretty good foundation of character sets, we can now continue our discussion of data types. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle SQL Tutorial 30 - UTF-8 and UTF-16 Character Sets
 
04:01
A few videos ago we discussed UTF-8 and UTF-16 encoding, but when we are working with a database we do not worry about encodings as much as we do character sets. That's because a specific character set is going to have a specific encoding. The reason I am making this video is to introduce you to the most common character sets and to teach you the differences. That’s because as we go into the national character sets we need to understand the information taught in this video. So the first character set I am going to teach you about is AL32UTF8. AL32UTF8 is a character set that uses the uff-8 encoding and each character can take up to 4 bytes with the utf-8 encoding. There is another character set (not encoding) called utf8 (no hyphen) which is also encoded with UTF-8. This can be a little confusing because UTF8 is the name of an encoding and a character set, but bear with me. Both of these character sets are UTF-8 encoded, but UTF8 uses an older version of UTF-8 encoding. Generally, they work about the same, but the way certain characters are stored is slightly different, specifically way certain characters are stored is slightly different, specifically what are known as supplementary characters, which take up 4 bytes. The max size for a UTF8 character set is 3 bytes, as they do not directly support the supplementary characters as 4 bytes but instead store them across 2 groups of 3 bytes each. Oracle recommends that you use AL32UTF8 for all future development instead of the archaic UTF8 character set. There is another character set that you should know about, and that is AL16UTF16, which uses the UTF-16 encoding. Watch my video over UTF-8 and UTF-16 to learn more about UTF-16. Lastly, there is a character set known as UTFE, which uses an encoding known as UTF-EBCDIC. This is like a super archaic character set, and I'm not even going to talk about it. I thought I would at least mention it as it is going to come up a bit in the next video's topic. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle SQL Tutorial 32 - VARCHAR2 and NVARCHAR2
 
03:06
This video we are going to discuss the VARCHAR2 and the NVARCHAR2 data types. The previous videos are a good foundation to this video. I've actually discussed so much stuff in those videos that I don’t have a whole lot to say. Good for you, right? I discussed over the previous videos that you should prefer to use VARCHAR2 over CHAR. That's because there is not a difference in performance or storage for a VARCHAR2 column. The only difference is that an CHAR column forces each value to take up a certain length even if it's not. There is one difference between the variable length and fixed length data types here that you need to know about, and that is storage limits. CHAR has a limit of 2000 bytes, while VARCHAR2 has a limit of 4000 bytes. That means you can store twice as much junk in a VARCHAR2 column! Other than that, these data types work exactly the same. I recommend you always use the VARCHAR2 data types instead of the CHAR data types, and only use NVARCHAR2 if you have a non-Unicode database. This will allow you to store Unicode characters in a column. Now, the amount of storage you can put in a VARCHAR2 column is twice what you can put in a CHAR column, but 4000 characters is still not very many characters. This is where the LOB data types come in, which we will discuss in the next video! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle SQL Tutorial 23 - Intro to Data Types
 
05:03
Every column within a table has to be given what is known as a datatype. A data type is a fairly simple concept when you dissect the word. It is literally the type of data. Why do we use types, though? The biggest benefit is so that Oracle knows how to interpret and work with our data. It also makes the database better at rejecting incorrect data. If we had to concept of a data type, there would be a lot more work involved in forcing data to be of the right format. It would also be harder for us to get the database to treat the data in the correct way. In addition to this, a database can optimize storage and performance for a column if everything is of the same data type. Because of this, each column can only support one data type. There are numerous different data types in Oracle and it helps us if we categorize them. The first types of datatypes we should learn about are: String, Numeric, Temporal Now, there are few more categories we could make, but these are the main ones. We will worry about the other ones another day as I am only introducing the topic. A string data type is anything within quotes. Most databases use single quotes for string data. Inside of the quotes can be any number of characters. What is a character? Think of any letter, number, or symbol you can type. Some people call these letters, numbers, and symbols alphanumeric. Numeric data type includes only numbers. These data types are often used for data that you plan on using for mathematical calculations. Temporal data types are data types that are used for dates and times. Now, each data type is probably going to have some options you'll need to worry about, but one that comes up with every data type is storage. The reason we need to consider storage is because we may end up with millions of rows in a table and the difference between a few bytes for each row will make a huge difference when we look at the whole picture. When a data type gives you the option of size, you will want to a size that will be able to hold what you need, but nothing more. In the upcoming videos we are going to discuss the available data types in more detail. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Every VARCHAR2(N) Declaration a Bug in PL/SQL!?
 
07:51
Every VARCHAR2(N) Declaration a Bug!? That's right. VARCHAR2 declarations mean that you have to provide an "N" or constraint on the size of the variable. If you have such declarations all over your code, that's a form of hard-coding and you are likely to get hammered by VALUE_ERROR exceptions. This video shows how to fix this problem.

Oracle SQL Tutorial 27 - CHAR Part 1
 
03:52
This video and the next is going to cover CHAR and NCHAR. Be sure to check out the previous two videos as these are going to introduce you to some foundational knowledge required to understand these data types. CHAR is a fixed-length data type. What that means is that every value for a CHAR column is going to be the same length. You specify the length in parenthesis when you create the table. The thing you need to know though is that the default measurement is in bytes. That means if you specify the length to be CHAR(50), the length of each value will be 50 bytes, by default. If you want to change that to 50 characters, you can pass in the word CHAR as in CHAR(50 CHAR). This is known as a qualifier. Specifically, they are known as length semantics qualifiers (describes the meaning of the given length). Now, I said the default was bytes, but you can actually change the default to characters. In that situation, you can actually use the keyword BYTE to break away from the default. In general, it's best to put CHAR or BYTE even if it is the default. In general, it's best to keep things consistent. It's okay to have these measured in CHAR or BYTE, but it is recommended that every column is the same. It allows you to be more consistent as if some columns measure length in bytes and some measure length in characters, things can get confusing. If you do want to change the default, look up NLS_LENGTH_SEMANTICS as well as the potential problems it may bring. What values are allowed in parenthesis? That is what we are going to discuss in the next video. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

From Java Code to Java Heap: Understanding the Memory Usage of Your Application
 
56:47
When you write and run Java code, the JVM makes several allocations on your behalf, but do you have an understanding of how much that is? This session provides insight into the memory usage of Java code, covering the memory overhead of putting "int" into an integer object and the cost of object delegation and the memory efficiency of the different collection types. It also gives you an understanding of the off-Java (native) heap memory usage of some types of Java objects, such as threads and sockets. Most importantly, the session covers how to determine where there are inefficiencies in your application and how to choose the right collections to improve your Java code.

String Functions in SQL Server part-V || SPACE, STR, STUFF, SUBSTRING functions in SQL
 
04:42
This video will provide you the details of each string functions in SQL Server 2014. I'll be walking through each and every kinds of build in function which are available in SQL Server in my next videos. Previous video for more String Functions String Function Part I https://www.youtube.com/watch?v=6cgn4... String Function Part II https://www.youtube.com/watch?v=RmyT8... String Function Part III https://www.youtube.com/watch?v=lQVnQ... String Function Part IV https://www.youtube.com/watch?v=cxASmU2hxjc ***************************************************************************************** SPACE (Transact-SQL) Returns a string of repeated spaces.  Syntax SPACE ( integer_expression )  Arguments integer_expression Is a positive integer that indicates the number of spaces. If integer_expression is negative, a null string is returned.  Return Types varchar STR (Transact-SQL) Returns character data converted from numeric data.  Syntax STR ( float_expression [ , length [ , decimal ] ] )  Arguments float_expression Is an expression of approximate numeric (float) data type with a decimal point. length Is the total length. This includes decimal point, sign, digits, and spaces. The default is 10. decimal Is the number of places to the right of the decimal point. decimal must be less than or equal to 16. If decimal is more than 16 then the result is truncated to sixteen places to the right of the decimal point.  Return Types varchar STUFF (Transact-SQL) The STUFF function inserts a string into another string. It deletes a specified length of characters in the first string at the start position and then inserts the second string into the first string at the start position.  Syntax STUFF ( character_expression , start , length , replaceWith_expression )  Arguments character_expression Is an expression of character data. character_expression can be a constant, variable, or column of either character or binary data. start Is an integer value that specifies the location to start deletion and insertion. If start or length is negative, a null string is returned. If start is longer than the first character_expression, a null string is returned. start can be of type bigint. length Is an integer that specifies the number of characters to delete. If length is longer than the first character_expression, deletion occurs up to the last character in the last character_expression. length can be of type bigint. replaceWith_expression Is an expression of character data. character_expression can be a constant, variable, or column of either character or binary data. This expression will replace length characters of character_expression beginning at start.  Return Types Returns character data if character_expression is one of the supported character data types. Returns binary data if character_expression is one of the supported binary data types. SUBSTRING (Transact-SQL) Returns part of a character, binary, text, or image expression in SQL Server.  Syntax SUBSTRING ( expression ,start , length )  Arguments expression Is a character, binary, text, ntext, or imageexpression. start Is an integer or bigint expression that specifies where the returned characters start. If start is less than 1, the returned expression will begin at the first character that is specified in expression. In this case, the number of characters that are returned is the largest value of either the sum of start + length- 1 or 0. If start is greater than the number of characters in the value expression, a zero-length expression is returned. length Is a positive integer or bigint expression that specifies how many characters of the expression will be returned. If length is negative, an error is generated and the statement is terminated. If the sum of start and length is greater than the number of characters in expression, the whole value expression beginning at start is returned.  Return Types Returns character data if expression is one of the supported character data types. Returns binary data if expression is one of the supported binary data types. The returned string is the same type as the specified expression with the exceptions shown in the table. Specified expression Return type char/varchar/text varchar nchar/nvarchar/ntext nvarchar binary/varbinary/image varbinary

Oracle Tattoo Concert
 
02:22
The Oracle Tattoo Concert (or Grand Concert) is inspired by traditional Polynesian body ornamentation. Those designs were monochromatic, tattooed in black against brown skin, with strongly geometric patterns, and many shapes and symbols inspired by the natural island world: stones, waves, fish, sharks, turtles, rain, sun, birds. What makes this guitar particularly special is an on-board USB input (which accommodates recording software) and a very competitive price. Other features include a solid spruce, top, mahogany back & sides, grand concert profile, rosewood fretboard, 25 1⁄2” scale and 1 11⁄16” Nut. Preamp/tuner B-band with 3- band EQ & USB On Board. Design by Alex Morgan. Featured Player Christie Lenée. For more on this guitar visit - http://bit.ly/1QHiwsm

Title: Weak Lower Bounds on Resource-Bounded Compression Imply Strong Separations of Complexity Classes Abstract: The Minimum Circuit Size Problem (MCSP) asks to determine the minimum size of a circuit computing a given truth table. MCSP is a natural and powerful string compression problem using bounded-size circuits. Recently, Oliveira and Santhanam [FOCS 2018] and Oliveira, Pich, and Santhanam [ECCC 2018] demonstrated a ``hardness magnification'' phenomenon for MCSP in restricted settings. Letting MCSP[s(n)] be the problem of deciding if a truth table of length 2^n has circuit complexity at most s(n), they proved that small (fixed-polynomial) average-case circuit/formula lower bounds for MCSP[2^{sqrt{n}}], or lower bounds for approximating MCSP[2^{o(n)}], would imply major separations such as NP not equal BPP and NP not in P/poly. We strengthen their results in several directions, obtaining magnification from worst-case lower bounds on exactly computing the search version of MCSP[s(n)], which also extend to time-bounded Kolmogorov complexity. Our main result is that search-MCSP (where we must output a s(n)-size circuit, when it exists) admits extremely efficient AC^0 circuits and streaming algorithms using Sigma_3-SAT oracle gates of small fan-in (related to the size s(n) we want to test). Here are a few byproducts. In all cases, the hypothesis looks like a rather weak-looking lower bound, but the consequence is an extremely strong lower bound: * For reasonable s(n) > = n, if search-MCSP[s(n)] does not have a 1-pass poly(s(n))-space streaming algorithm with poly(s(n)) update time, then P != NP. For example, proving that it is impossible to synthesize circuits of size 2^{n/log^{star} n} with a streaming algorithm on truth tables of length N=2^n using N^{eps} update time and N^{eps} space (for some eps > 0) would already separate P and NP. Note that some extremely simple functions, such as EQUALITY of two strings, already satisfy such lower bounds. * If for some c >= 1, search-MCSP[n^c] does not have tilde{O}(N)-size, tilde{O}(1)-depth circuits, then NP is not in P/poly. * If search-MCSP[s(n)] does not have N*poly(s(n))-size, O(log N)-depth circuits, then NP is not in NC^1. Note it is known that MCSP[2^{sqrt{n}}] does not have formulas of N^{2.99} size [Cheraghchi-Kabanets-Lu-Myrisiotis, ECCC 2019]. * If there is an eps>0 such that for all c >= 1, search-MCSP[2^{n/c}] does not have N^{1+eps}-size O(1/eps)-depth ACC^0 circuits, then NP is not in ACC^0. Thus the amplification ideas of Allender and Kouck{\'y} [JACM 2010] can extend to problems in NP (and beyond). Joint work with Cody Murray and Dylan McKay, to appear in STOC 2019
