In this paper the author presents three approaches to parallel Tabu Search, applied to several instances of the Capacitated Vehicle Routing Problem with soft Time Windows (CVRPsTW). The Tabu Search algorithms are of two kinds: Two of them are parallel with respect to functional decomposition and one approach is a collaborative multisearch TS. The implementation builds upon a framework called Distributed metaheuristics or DEME for short. Tests were performed on an SGI Origin 3800 supercomputer at the Johannes Kepler University of Linz, Austria.
