利用遗传算法计算目标函数极值，遗传算法与传统的优化方法（枚举，启发式等）相比较，以生物进化为原型，具有很好的收敛性，在计算精度要求时，计算时间少，鲁棒性高等都是它的优点。(Using the genetic algorithm to calculate the extremum of a objective function. Compared with the traditional optimization methods (enumeration, heuristics, etc.), genetic algorithms take the biological evolution as the prototype, which has good convergence. It has the advantages of less computational time and high robustness when calculating the precision requirements .)
