121PPAD (complexity) — PPAD is a complexity class, standing for Polynomial Parity Arguments on Directed graphs . Introduced by Christos Papadimitriou in 1994, PPAD is a subclass of TFNP based on functions that can be shown to be total by a parity argument. [cite… …
122PCP (complexity) — In computational complexity theory, PCP is the class of decision problems having probabilistically checkable proof systems. Introduction and definition In complexity theory, a PCP system can be viewed as an interactive proof system in which the… …
123FNP (complexity) — In computational complexity theory, the complexity class FNP is the function problem extension of the decision problem class NP. The name is a bit of a misnomer, since technically it is a class of binary relations, not functions, as the following …
124Advice (complexity) — Advice is a concept in complexity theory. An advice string is an extra input to a Turing machine which is allowed to depend on the length n of the input, but not on input itself. A decision problem is in the complexity class P/f(n) if there is a… …
125AC (complexity) — In circuit complexity, AC is a complexity class hierarchy. Each class, ACi, consists of the languages recognized by Boolean circuits with depth O(log^i n) and a polynomial number of unlimited fanin AND and OR gates.The smallest AC class is AC0,… …
126Institute for Mathematics Complexity and Cognition — The Institute for Mathematics Complexity and Cognition (MC2) of the Center for Advanced Defense Studies brings together scientists from the government, academia and the private sector to examine the foundations of mathematical theories of… …
127Rademacher complexity — In statistics and machine learning, Rademacher complexity measures richness of a class of real valued functions with respect to a probability distribution.Let mathcal{F} be a class of real valued functions defined on a domain space Z.The… …
128Cyclomatic complexity — Die McCabe Metrik (auch zyklomatische Komplexität cyclomatic complexity) ist eine Software Metrik, mit der die Komplexität eines Software Moduls gemessen werden kann. Die zyklomatische Komplexität wurde bereits 1976 durch Thomas J. McCabe… …
