Abstract
This work focuses on the computational efficiency of timed tissue P system. A rule in traditional P systems is usually executed in one time unit. We investigate the timed tissue P systems by removing the restriction. It is constructed by adding a time mapping to the rules to specify the execution time for each rule. A uniform and time-free solution to vertex cover problem is proposed, where the execution time of the computational processes involved can vary arbitrarily and the output produced is always the same.
