有点off-topic, 所以直接给结果
16人最多可以打五场, 每个人都不重复对上 (两个参考解)
16/5 240(best) (每串是一场, 从前面开始每四个数字配在一组, 以此类推)

而32人打8场 目前还没找出不重复对上的解, 但是有不错的排法(尽量不会重复到)

使用的方式是启发式算法程式暴力搜寻 随机起点 单用greedy找local optimal
到达local optimal之后不作跳出山谷的处理, 直接重新随机一个起点做下去
再从暂时的结果里面挑一个看起来比较顺眼的

快推不然别人以为我看不懂

不愧是练ACM出来的

吐了，有点晕车的感觉

对不起QQ

看久了觉得我好像不认识阿拉伯数字了...

推，16人5场的我曾经手动排过，32人就没想过了XDhttp://i.imgur.com/qPq5OnO.png 16人5场示意图

太复杂了吧..

要排赛程让每个选手都平均对到的条件有两个 若总人数为n则满足1.n是4的倍数 2.n-1是3的倍数 就可以办到联立解出4+12n，所以4人，16人，28人，40人都可以公平排不过没考虑选手相性问题 其他数字的话只能大概逼近而已
