FP (complexity class)
In theoretical computer science, especially complexity theory , the class FP describes the set of all search problems that can be solved by a deterministic Turing machine in polynomial time ( English function polynomial time , hence the abbreviation). Put simply, these are all search problems that can be efficiently solved on a classic computer.
definition
A left total relation is in FP if there is a deterministic algorithm that calculates a given in polynomial time , so that .
It restricts additionally quite clear relations and to truth values, you get exactly the complexity class P .
Analogous to the class NP , a more general class can define FNP . The only requirement for elements in this class is that it can be determined deterministically for a given pair of values in polynomial time whether the following applies.
