(definition)
Definition: The class of languages for which a membership computation by a probabilistic Turing machine halts in polynomial time with the right answer (accept or reject) at least 2/3 of the time. "BPP" means "Bounded error Probability in Polynomial" time.
Also known as bounded error probability in polynomial time.
See also ZPP, RP, NP, complexity class.
Note: By repeating the run, the chance of error may be arbitrarily reduced.
After [Hirv01, page 19].
