چکیده انگلیسی
This paper presents a general optimization model gleaned ideas from the coevolution of symbiotic species in natural ecosystems. Species extinction and speciation events are also considered in this model to tie it closer to natural evolution, as well as improve the algorithm robustness. This model is instantiated as a novel multi-species optimizer, namely PS2O, which extends the dynamics of the canonical PSO algorithm by adding a significant ingredient that takes into account the symbiotic coevolution between species. When tested against benchmark functions, the PS2O markedly outperforms the canonical PSO algorithm in terms of accuracy, robustness and convergence speed.
