多人游戏锦标赛发生器[关闭]-Java 学习之路

如果我有一个多人游戏，每场游戏需要6个人，而且我有100个锦标赛参与者，那么我可以用什么算法将人们分配给游戏，这样每个人至少互相玩一次，同时最大限度地减少游戏玩家的数量会扮演他们已经玩过的人吗？

从本质上讲，有没有办法为多人游戏产生循环赛？我正在考虑将此算法用于Catan锦标赛 .

处理相关社交高尔夫球手问题的方法之一是本地搜索 . 一些提出的方法非常复杂 . 下面的C程序不是;它选择一个随机的初始时间表并进行随机交换，这不会增加不玩的玩家对的数量 . 100名玩家和6人组需要至少21轮（一些玩家坐在一轮，然后需要ceil（（100 - 1）/（6 - 1））= 20轮来玩每个人），所以27不是虽然我确信使用更复杂的优化技术可以做得更好，但距离最佳值太远了 .
