有點off-topic, 所以直接給結果
16人最多可以打五場, 每個人都不重覆對上 (兩個參考解)
16/5 240(best) (每串是一場, 從前面開始每四個數字配在一組, 以此類推)

使用的方式是啟發式演算法程式暴力搜尋 隨機起點 單用greedy找local optimal
到達local optimal之後不作跳出山谷的處理, 直接重新隨機一個起點做下去
再從暫時的結果裡面挑一個看起來比較順眼的

快推不然別人以為我看不懂

不愧是練ACM出來的

吐了，有點暈車的感覺

對不起QQ

看久了覺得我好像不認識阿拉伯數字了...

推，16人5場的我曾經手動排過，32人就沒想過了XDhttp://i.imgur.com/qPq5OnO.png 16人5場示意圖

太複雜了吧..

要排賽程讓每個選手都平均對到的條件有兩個 若總人數為n則滿足1.n是4的倍數 2.n-1是3的倍數 就可以辦到聯立解出4+12n，所以4人，16人，28人，40人都可以公平排不過沒考慮選手相性問題 其他數字的話只能大概逼近而已
