Connector-Breaker games on random boards
Abstract
By now, the Maker-Breaker connectivity game on a complete graph or on a random graph is well studied. Recently, London and Pluh\'ar suggested a variant in which Maker always needs to choose her edges in such a way that her graph stays connected. By their results it follows that for this connected version of the game, the threshold bias on and the threshold probability on for winning the game drastically differ from the corresponding values for the usual Maker-Breaker version, assuming Maker's bias to be . However, they observed that the threshold biases of both versions played on are still of the same order if instead Maker is allowed to claim two edges in every round. Naturally, this made London and Pluh\'ar ask whether a similar phenomenon can be observed when a game is played on . We prove that this is not the case, and determine the threshold probability for winning this game to be of size .
