Abstract: Considering the premature convergence problem of Fruit fly Optimization Algorithm(FOA), a new collaborative learning FOA based on the best and the worst individual is presented. The evolutionary equation is optimized by adding learning the worst individual to it. The ability of the algorithm to break away from the local optimum and to find the global optimum is greatly enhanced. Experimental results show that the new algorithm has the advantages of better global search ability, speeder convergence and more precise convergence.

摘要： 针对果蝇优化算法的早熟收敛问题，提出一种基于最优和最差个体协同学习的果蝇优化算法。该算法通过在进化方程中添加向最差个体学习的改进策略，优化进化方程，增强算法跳出局部最优、寻找全局最优的能力。对经典测试函数的仿真结果表明，该算法具有更好的全局搜索能力，在收敛速度、收敛可靠性及收敛精度上比其他算法有较大的提高。
