遗传算法是一种模拟生物进化机制的随机全局优化搜索方法，具有很强的全局优化能力及鲁棒性。遗传算法属于直接搜索法，对适应函数基本无限制，既不要求连续，也不要求函数可微，而且不需要初始信息可以寻求全局最优解克服了单纯形算法初始条件影响大，易陷入局部最小等缺点，操作方便，速度快，不需要复杂的规则，且可用于多目标寻优，在解空间进行高效启发式搜索，可以提高运算速度。-The genetic algorithm is one simulation organic evolution mechanism stochastic global optimization reconnaissance method, has the very strong global optimization ability and robustness. The genetic algorithm belongs to the direct search method, to adapts the function basically unlimited, also does not request continual, also does not request the function differentiable, moreover did not need the initial information to be possible to seek the globally optimal solution to overcome the simplex algorithm initial condition to affect in a big way, easy to fall into is partially smallest and so on shortcomings, the ease of operation, the speed is quick, did not need the complex rule, and might use in the multi-objective optimizations, carried on the highly effective heuristic search in the solution space, might raise the operating speed.
