environments. To efficiently exploit the search space, the algorithm divides each dimension into some regions, and each dimension is evaluated separately. Also, inspired by the immune memory concept, a memory-based approach is proposed to store and retrieve the most important information when a change occurs. Furthermore, to increase the convergence speed, a new clonal selection method is proposed. Lastly, the efficiency of the algorithm is compared to that of other immune-based algorithms on the MPB. The experimental results confirm that the proposed method is competitive to optimize dynamic problems.
