甲乙兩人在玩一個機率遊戲。
每一回合裡:
甲和乙各自從[0,1]取一個實數,
選好後一起公開, 並把自己選的x值輸入給隨機系統作評判.
隨機系統有x的機率回傳"Yes", 有(1-x)的機率回傳"No".
若甲乙都收到"Yes", 則x值較小的一方得1分.
若一方收到"Yes", 另一方收到"No", 則收到"Yes"的一方得1分.
若甲乙都收到"No", 則大家都不得分.
若剛好甲乙都收到"Yes"且彼此的x值相等, 則大家各得0.5分.
新的回合要取新的x, 不停的比下去, 累積比分,
在某一定回合(如10回合)後比總分, 分數多方獲勝.
假設甲乙都是絕對理性,
請問: 他們將採取什麼樣的策略才能讓自己不敗呢?
