Abstract: Online contention resolution schemes is a general technique for Bayesian selection problems such as prophet inequalities, oblivious posted pricing mechanisms, and stochastic probing models.

In this tutorial we are going to introduce these techniques in the simplest single item setting and then discuss how to generalize it to the more rich matroid constrained setting. We also point out close connections to matroid secretary and matroid prophet problems.
