In theoretical computer science, an algorithm is correct with respect to a specification if it behaves as specified. Best explored is functional correctness, which refers to the input-output behavior of the algorithm (i.e., for each input it produces an output satisfying the specification). Within the latter notion, partial correctness, requiring that if an answer is returned it will be correct, is distinguished from total correctness, which additionally requires that an answer is eventually r… WebJun 19, 2015 · People who make these proofs are either algorithm designers (you do not publish an algorithm without some kind of proof), or proof specialist for complex … slowpoke location lets go eevee
