In complexity theory, PP is the class of decision problems solvable by a probabilistic Turing machine in polynomial time, with an error probability of less than 1/2 for all instances. The abbreviation PP refers to probabilistic polynomial time. The complexity class was defined by Gill in 1977. If a decision problem … Visa mer A language L is in PP if and only if there exists a probabilistic Turing machine M, such that • M runs for polynomial time on all inputs • For all x in L, M outputs 1 with probability strictly greater than 1/2 Visa mer BPP is a subset of PP; it can be seen as the subset for which there are efficient probabilistic algorithms. The distinction is in the error … Visa mer Unlike BPP, PP is a syntactic, rather than semantic class. Any polynomial-time probabilistic machine recognizes some language in PP.
