Pseudo-deterministic Algorithms (Invited Talk)

Shafi Goldwasser
In this talk we describe a new type of probabilistic algorithm which we call "Bellagio" Algorithms: a randomized algorithm which is guaranteed to run in expected polynomial time, and to produce a correct and unique solution with high probability. These algorithms are pseudo-deterministic: they can not be distinguished from deterministic algorithms in polynomial time by a probabilistic polynomial time observer with black box access to the algorithm. We show a necessary and sufficient condition for...
