In this talk, we describe a new type of probabilistic algorithm (introduced by Gat and Goldwasser [GG11]) called Pseudo-deterministic Algorithms: a randomized algorithm which is guaranteed to run in expected polynomial time and to produce a correct and unique solution with high probability.
The name comes from the fact that 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 will discuss some interesting algorithms as well as open problems. We will also look at  Pseudo-deterministic Algorithms from a complexity point of view.
