Original Abstract

The Bayesian Optimization Algorithms (BOA) belong to the probabilistic model building evolutionary algorithms where crossover and mutation operators are replaced by probability distribution estimation and sampling techniques. The learned Bayesian network BN as the most general graphical probability model is used to encode the structure of solved combinatorial problems. In [1] we proposed and simulated the pipeline hardware architecture for BOA. The aim of this paper is to propose the distributed version of BOA algorithm with a coarse-grained parallelism. We focused primarily on the construction of Bayesian network in the distributed environment. In addition, methods for overlapping the communication latency during generation, evaluation and broadcasting of new population among the processes are described. Much attention was devoted to the implementation of proposed approaches using a cluster of workstations as a computational platform.
