Title: Randomness and determinism in Ramsey theory
Abstract: For many decades randomness proved to be the central paradigm in Ramsey theory. Recent results suggest, however, that optimal constructions in the field may involve a subtle blend of randomness and determinism. We will illustrate this by surveying many recent results, mainly about graph and hypergraph Ramsey numbers.
