Block cellular automaton — The Margolus neighborhood for a two dimensional block cellular automaton. The partition of the cells alternates between the set of 2 × 2 blocks indicated by the solid blue lines, and the set of blocks indicated by the dashed red lines. A block… … Wikipedia
Function object — A function object, also called a functor or functional, is a computer programming construct allowing an object to be invoked or called as if it were an ordinary function, usually with the same syntax.Function objects are unrelated to functors in… … Wikipedia
Block (programming) — In computer programming, a block is a section of code which is grouped together. Blocks consist of one or more declarations and statements. A programming language that permits the creation of blocks, including blocks nested within other blocks,… … Wikipedia
One-way compression function — In cryptography, a one way compression function is a function that transforms two fixed length inputs to an output of the same size as one of the inputs. The transformation is one way , meaning that it is difficult given a particular output to… … Wikipedia
Map (higher-order function) — In many programming languages, map is the name of a higher order function that applies a given function to each element of a list, returning a list of results. They are examples of both catamorphisms and anamorphisms. This is often called apply… … Wikipedia
Cryptographic hash function — A cryptographic hash function (specifically, SHA 1) at work. Note that even small changes in the source input (here in the word over ) drastically change the resulting output, by the so called avalanche effect. A cryptographic hash function is a… … Wikipedia
Hash function — A hash function is any well defined procedure or mathematical function for turning some kind of data into a relatively small integer, that may serve as an index into an array. The values returned by a hash function are called hash values, hash… … Wikipedia
Primitive recursive function — The primitive recursive functions are defined using primitive recursion and composition as central operations and are a strict subset of the recursive functions (recursive functions are also known as computable functions). The term was coined by… … Wikipedia
Heuristic function — A heuristic function or simply a heuristic is a function that ranks alternatives in various search algorithms at each branching step basing on an available information in order to make a decision which branch is to be followed during a… … Wikipedia
