Abstract

In this paper we describe an efficient parallel synchronized branch and bound (PSBB) algorithm for distributed memory parallel computers. The parallelization of the sequential best-first branch and bound algorithm is based on the concept of alternating computation and synchronization steps. The computational steps simplify the problem to solve whereas the synchronization phases solve the problem of load balancing and data distribution. Experimental results show the efficiency of the proposed PSBB algorithm when solving traveling salesman problems on a massively parallel Cray T3D machine.
