Abstract
Real or academic combinatorial optimization problems are in the majority NP-hard. For large dimensions, an exact resolution is often impractical due to a limited amount of resources. The use of large scale deployment on distributed systems such as peer-to-peer (P2P) systems, based on exploiting free CPU cycles, provides an efficient way to reach high computing performance by distributing the computation to solve these problems. In this paper, we are interested in solving exactly optimization problems using parallel branch-and-bound algorithm on large scale distributed systems. We propose ParallelBB, which is a parallelization of the branch-and-bound algorithm and apply it to a mono-criterion permutation flow-shop problem. Furthermore, we develop P2PBB, which is the peer-to-peer implementation of our algorithm using ProActive
