Motivated by the longstanding Caccetta-Häggkvist Conjecture, Kelly, Kühn and Osthus made a conjecture on the minimal semi-degree forcing the appearance of a directed cycle of a given length, and proved it for cycles of length not divisible by 3. In the talk we will present an overview of a proof of all the remaining cases of their conjecture with the optimal semi-degree threshold. This is joint work with Roman Glebov and Jan Volec.
