Average-Time Games

Abstract

An average-time game is played on the infinite graph of
configurations of a finite timed automaton.
The two players, Min and Max, construct an infinite run of the
automaton by taking turns to perform a timed transition.
Player Min wants to minimize the average time per transition and
player Max wants to maximize it.
A solution of average-time games is presented using a reduction to
average-price game on a finite graph.
A direct consequence is an elementary proof of determinacy for
average-time games.
This complements our results for reachability-time games and
partially solves a problem posed by Bouyer et al., to design an
algorithm for solving average-price games on priced timed
automata.
The paper also establishes the exact computational complexity of
solving average-time games: the problem is EXPTIME-complete for
timed automata with at least two clocks.
