Abstract
We show the solvability of an optimization problem on infinite two-player games. The winning conditions are of the “request-response” format, i.e. conjunctions of conditions of the form “if a state with property Q is visited, then later a state with property P is visited”. We ask for solutions that do not only guarantee the satisfaction of such conditions but also minimal wait times between visits to Q-states and subsequent visits to P-states. We present a natural class of valuations of infinite plays that captures this optimization problem, and with respect to this measure show the existence of an optimal winning strategy (if a winning strategy exists at all) and that it can be realized by a finite-state machine. For the latter claim we use a reduction to the solution of mean-payoff games due to Paterson and Zwick.
