Hitting time results for Maker-Breaker games
Abstract
We study Maker-Breaker games played on the edge set of a random graph. Specifically, we consider the random graph process and analyze the first time in a typical random graph process that Maker starts having a winning strategy for his final graph to admit some property . We focus on three natural properties for Maker's graph, namely being -vertex-connected, admitting a perfect matching, and being Hamiltonian. We prove the following optimal hitting time results: with high probability Maker wins the -vertex connectivity game exactly at the time the random graph process first reaches minimum degree ; with high probability Maker wins the perfect matching game exactly at the time the random graph process first reaches minimum degree ; with high probability Maker wins the Hamiltonicity game exactly at the time the random graph process first reaches minimum degree . The latter two statements settle conjectures of Stojakovi\'{c} and Szab\'{o}.
