You take a problem that you can't solve with a pure mathematical answer, you build an evolutionary system to try multiple tries at guessing, you add sex -- where you take half of one solution and half of another and then make new mutations -- and you use natural selection to kill off not as good solutions.
当你遇到不能用纯数学的方法来解决的问题， 可以建立一个类似进化的系统， 通过猜测可能的解来进行求解的过程， 你设立繁殖过程-- 在这个过程中，用各自两个可能解的一半来繁殖产生新的可能解-- 然后用自然选择的原理来舍弃不好的肯能解。
