但是切换到3个人以后好像就完全没有规律了,n个数时3人输的概率分别为
[1 1/2 1/3 1/4 1/5 1/6 1/7 1/4 1/3 2/5 5/11 1/4 3/13 3/14 1/5 1/4 5/17 1/3 7/19 7/20 1/3 7/22 5/23 7/24 7/25 7/26 8/27 9/28 9/29 3/10 9/31 9/32 3/11 9/34 11/35 11/36 12/37 13/38 1/3 13/40 13/41 13/42 13/43 13/44 13/45 15/46 16/47 17/48 16/49 3/10 5/17 4/13 17/53 17/54 18/55 19/56 1/3 19/58 19/59 3/10 19/61 19/62 20/63 21/64 21/65 1/3 22/67 11/34 22/69 11/35 22/71 23/72 24/73 25/74 1/3 25/76 25/77 25/78 25/79 5/16 26/81 27/82 27/83 1/3 28/85 14/43 28/87 7/22 29/89 29/90 29/91 15/46 1/3 31/94 32/95 1/3 31/97 31/98 32/99 33/100]
[0 1/2 2/3 1/2 2/5 1/3 2/7 1/4 2/9 1/5 4/11 5/12 6/13 3/7 2/5 3/8 6/17 1/3 6/19 7/20 8/21 9/22 10/23 1/3 8/25 4/13 8/27 9/28 10/29 11/30 12/31 3/8 4/11 6/17 2/7 5/18 10/37 13/38 14/39 7/20 14/41 1/3 14/43 7/22 14/45 6/23 14/47 1/3 17/49 9/25 6/17 9/26 18/53 8/27 16/55 9/28 1/3 10/29 20/59 11/30 21/61 10/31 20/63 21/64 22/65 1/3 23/67 6/17 8/23 12/35 24/71 23/72 24/73 12/37 8/25 13/38 26/77 9/26 27/79 27/80 1/3 27/82 25/83 13/42 29/85 15/43 10/29 15/44 30/89 1/3 29/91 29/92 1/3 16/47 32/95 1/3 34/97 33/98 1/3 33/100]
[0 0 0 1/4 2/5 1/2 4/7 1/2 4/9 2/5 2/11 1/3 4/13 5/14 2/5 3/8 6/17 1/3 6/19 3/10 2/7 3/11 8/23 3/8 2/5 11/26 11/27 5/14 10/29 1/3 10/31 11/32 4/11 13/34 2/5 5/12 15/37 6/19 4/13 13/40 14/41 5/14 16/43 17/44 2/5 19/46 17/47 5/16 16/49 17/50 6/17 9/26 18/53 7/18 21/55 19/56 1/3 19/58 20/59 1/3 21/61 23/62 23/63 11/32 22/65 1/3 22/67 11/34 1/3 12/35 25/71 13/36 25/73 25/74 26/75 25/76 26/77 1/3 27/79 7/20 28/81 14/41 31/83 5/14 28/85 14/43 1/3 15/44 30/89 31/90 33/91 33/92 1/3 31/94 31/95 1/3 32/97 17/49 34/99 17/50]
而选择的对称在3个数是选中间,4个数也是选中间两个,但是5个数只要不选两边就可以。6,7,8个数还是选中间,9个数选中间3个,10个数选中间4个,11个数选两边各两个(1,2,10,11),12~18个数时都神奇的选择了12号数(或对称的数,比如12个数时1,12对称,18个数时,7,18对称)。
19个数时选择方案较多有(1,2,8,12,18,19),20个数时可以选择(1,2,9,12,19,20),21个数选(2,10,12,20) ,22个数选(11,12), 23个数只能选12,24个数可以选(2,3,4,12,13,21,22,23), 25个数选(3,4,12,14,22,23)
(需要注意神奇的12还没有退出)
但是26个数时,12号数终于退出最优选择,需要选(4,23)
27个数,选(5,23),
但是到了28~34个数,神奇的12又回归了(只能选12以及对称数)
而35个数可以选(4,12,13,14,...)
总体上来说,12号数是很受欢迎的
比如前500个数里面找出编号最小的最优选择,结果如下(也就是如果还有比12更小的最优选择,12就不会被显示)
[1, 1, 2, 2, 2, 3, 4, 4, 4, 4, 1, 1, 2, 3, 4, 5, 6, 7, 1, 1, 2, 11, 12, 2, 3, 4, 5, 12, 12, 12, 12, 12, 12, 12, 4, 14, 15, 19, 20, 2, 2, 3, 4, 22, 23, 23, 23, 10, 1, 12, 12, 4, 5, 23, 23, 3, 19, 20, 20, 12, 12, 23, 23, 12, 12, 18, 19, 12, 12, 12, 23, 4, 12, 21, 22, 12, 12, 12, 12, 12, 12, 12, 23, 23, 12, 12, 39, 12, 12, 12, 23, 23, 12, 12, 2, 1, 49, 12, 4, 4, 12, 12, 1, 1, 12, 12, 12, 12, 12, 23, 12, 12, 12, 12, 12, 12, 12, 23, 12, 12, 12, 1, 12, 12, 3, 4, 12, 12, 12, 22, 23, 3, 12, 12, 12, 4, 12, 23, 23, 12, 12, 2, 3, 12, 12, 4, 12, 12, 12, 2, 49, 12, 49, 12, 12, 12, 49, 12, 12, 12, 3, 12, 12, 12, 12, 12, 12, 12, 12, 12, 49, 3, 12, 12, 12, 23, 12, 12, 12, 12, 12, 4, 12, 12, 12, 2, 12, 4, 12, 12, 12, 12, 12, 23, 12, 12, 12, 12, 12, 49, 12, 12, 12, 12, 12, 22, 12, 104, 12, 12, 3, 12, 12, 12, 12, 12, 12, 49, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 23, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 122, 12, 2, 3, 4, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 23, 12, 12, 12, 12, 12, 22, 23, 23, 12, 12, 12, 49, 12, 12, 3, 12, 12, 23, 2, 1, 2, 3, 4, 12, 12, 12, 12, 12, 12, 49, 12, 12, 12, 12, 23, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 20, 12, 12, 12, 3, 12, 23, 12, 23, 12, 12, 12, 12, 12, 12, 12, 12, 12, 2, 12, 4, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 49, 12, 12, 12, 12, 12, 12, 12, 3, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 2, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 104, 12, 12, 3, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 3, 12, 12, 12, 12, 12, 12, 12, 12, 12, 49, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 23, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 49, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 244, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 49, 12]
而如果换成4个选手好像48号数比较受欢迎,但是受欢迎程度和3个选手时的12完全不能相比
