BPP

(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].
