Atlantic City algorithm
Atlantic City algorithm is a probabilistic polynomial time algorithm that answers correctly at least 75% of the time. The term "Atlantic [City, New Jersey|Atlantic City]" was first introduced in 1982 by J. Finn in an unpublished manuscript entitled Comparison of probabilistic tests for primality.
Two other common classes of probabilistic algorithms are Monte [Carlo algorithm]s and Las Vegas algorithms. Monte Carlo algorithms are always fast, but only probably correct. On the other hand, Las Vegas algorithms are always correct, but only probably fast. The Atlantic City algorithms, which are bounded probabilistic polynomial time algorithms are probably correct and probably fast.
