主题：【原创】征婚兼求教 -- 风萧萧

她的CANDIDATE出现是随机的，entirely random and unpredictable. Not a given ensemble which are totally under your control.

象射击里的随即移动靶。你的破公式只能搞好静止靶. She can only keep very limited number of candidates in hand. So she has to make decision of rejecting those apparently non-qualified or potentially non-qualified as fast as she can.

A useful strategy: Always keep two candidates in hand. Compare them, but use one reject another. Then pull a new one in. Make further comparison. Keep the good one and abandon the bad one.
