%0 Journal Article %T Game Characterizations of Timed Relations for Timed Automata Processes %A Shibashis Guha %A Shankara Narayanan Krishna %J Computer Science %D 2012 %I arXiv %X In this work, we design the game semantics for timed equivalences and preorders of timed processes. The timed games corresponding to the various timed relations form a hierarchy. These games are similar to Stirling's bisimulation games. If it is the case that the existence of a winning strategy for the defender in a game ${\cal G}_1$ implies that there exists a winning strategy for the defender in another game ${\cal G}_2$, then the relation that corresponds to ${\cal G}_1$ is stronger than the relation corresponding to ${\cal G}_2$. The game hierarchy also throws light into several timed relations that are not considered in this paper. %U http://arxiv.org/abs/1206.6565v1
