摘 要: 针对过程综合混合整数非线性规划问题提出了一种混合遗传算法,该算法对整数变量进行编码,而对连续变量则采用连续化遗传算子进行处理,使得算法与原问题的对应更加自然,也更有效。另外,还针对常见的提前收敛或局部最小现象提出几种算子,实例表明本算法具有较强的全局优化能力。相对于传统遗传算法具有速度快、精度高、可操作性强等特点。 A new mixed genetic algorithm for the problem of MINLP is set up in the article. In order to solve the problem of MINLP effectively and naturally, continous genetic operators are used for continous variables and traditional ones for integer. At the same time, several operators are set up to deal with the usual phenomenon of premature convergence and local optimum. Example shows that the way has the ability of finding the global optimum with higher speed and better precision than traditional genetic algorithm.
