 Post subject: [问题]过年分金币了,大家都来拿吧

有5个死犯,一袋金币100枚。
现从1-5号轮流拿取金币,大家不知道别人拿了多少,但是每个人拿的时候可以知道袋子里的剩余数量;最少1枚,最多可以全部取走。
最后大家摊牌,拿最多和最少的人杀掉。并列最值一样杀掉。
假设大家都是聪明的,都希望先保命,再杀人。
问,如果你在其中,你用什么策略,你会排在几号?(也就是问几号生存几率最大) Smile

实在想不出来的话,家里人多的或者在办公室的,大家可以找个袋子抓抓,互相先杀杀看。还有活着的,回个贴上来。 Twisted Evil

有5个家伙,拾到一袋金币100枚,法律规定如下:
现从1-5号轮流拿取金币,大家不知道别人拿了多少,但是每个人拿的时候可以知道袋子里的剩余数量;最少1枚,最多可以全部取走。
最后大家摊牌,拿最多和最少的人金币充公。并列一样多金币也充公。

假设大家都是聪明的,都希望赢得自己拿到的金币。
问,如果你在其中,你用什么策略,你会排在几号?(也就是问几号白拿金币几率最大)

实在想不出来的话,家里人多的或者在办公室的,大家可以找个袋子抓抓,互相先看看。有白拿金币的,上来冒个泡。

这是个道德问题;
如果智商没问题;应该是全死;
如果第1个决策错误;第2个机会很大;但第1个必死,除非后面4人智商有问题;
对第1人来说有3种情况:全死、自己死救别人、不想死,期望后面4人都犯错误;所以不能做第1人;
但第2人,只需要第1人犯错误即可以活;还有就算第1人选择“正确”,第2人也只要求3人都正确才会死;所以,权衡一下,应该选第2人;

如果第1人是品德高尚的人,应该牺牲最小为原则,应该拿94个;这样只要自己和其中1人死就可以;

第3、4、5的命运都是掌握在别人手里,而且危险是越来越大;第5基本也是必死;

如果第一个人坏,拿走全部的100个,那他是最多的,其他4人拿到的都是0个,都是最少的,所以这5个人都要死;
