Clonal Selection Algorithm parallelization with MPJExpress

This paper exploits the parallelism potential on a Clonal Selection Algorithm (CSA) as a parallel metaheuristic algorithm, due the lack of explanation detail of the stages of designing parallel algorithms. To parallelise population-based algorithms, we need to exploit and define their granularity for each stage; do data or functional partition; and choose the communication model. Using a library for a message-passing model, such as MPJExpress, we define appropriate methods to implement process communication. This research results pseudo-code for the two communication message-passing models, using MPJExpress. We implemented this pseudo-codes using Java Language with a dataset from the Travelling Salesman Problem (TSP). The experiments showed that multicommunication model using alltogether method gained better performance that master-slave model that using send-and receive method.
