—Many optimization problems in real world are dynamic in the sense that the global optimum value and the shape of fitness function may change with time. The task for the optimization algorithm in these environments is to find global optima quickly after the change in environment is detected. In this paper we describe a novel algorithm, which we have called DPSABC, and show that it can be applied to dynamic optimization problems. The core of this algorithm is using PSO to optimize the fitness value of population in ABC. Experimental results on various dynamic environments modeled by the moving peaks benchmark show that the proposed algorithm outperforms other algorithms, like mQSO, adaptive mQSO and RPSO.
