摘要
针对灰色约束非线性规划问题,设计了一种改进蚁群算法.该算法采用了正反馈机制,在对灰色约束非线性规划问题白化处理后,将罚函数方法引入到目标函数中,同时给出了改进蚁群算法的仿真流程.实例应用表明,将改进后的蚁群算法应用于灰色约束非线性规划问题的求解是可行有效的.
An improved ant colony algorithm was proposed to solve the grey constrained nonlinear programming problem. Positive feedback mechanism was adopted in this algorithm. On the basis of whitening the grey constrained nonlinear programming problem, penalty function method was introduced in the objective function. A detailed programming flow-chart was also presented. The practical simulation results show that the improved ant colony algorithm is feasible and effective in solving grey constrained nonlinear programming problem.
