In light of the poor convergence problems and the diversity of current multi-objective optimization algorithms, in this paper, we propose an objective-space decomposition and continuous mutation-based multi-objective particle-swarm-optimization algorithm. Its innovations are as follows:we use a space decomposition method to distribute the particle swarm into a predefined sub-region. During this process, we apply a new adaptive value formula to select and filter the particles in each sub-region and incorporate a fitness formula into the dominance factor. In the global search process, we apply differential, Gaussian, and Cauchy mutations to continuously mutate the position of the global guide particle. We compare the performance of this algorithm with those of current multi-objective optimization algorithms, and the results show that the proposed algorithm improves the convergence and diversity of the particles.
