OPSOCM: Opposition based PSO with Cauchy Mutation.

Earthworms can aerate the soil with their burrowing action and enrich the soil with their waste nutrients. Inspired by the earthworm contribution in nature, a new kind of bio-inspired metaheuristic algorithm, called earthworm optimization algorithm (

粒子群优化研究工具箱是为了协助解决粒子群优化（PSO）过早收敛问题的论文研究。(Gbest PSO, Lbest PSO, RegPSO, GCPSO, MPSO, OPSO, Cauchy mutation, and hybrid combinations)

利用柯西突变策略和莱维飞行策略来提高GBO算法的开发和探索能力(The Cauchy mutation strategy and Levy flight strategy are used to improve the development and exploration ability of GBO algorithm)
