在河的右岸上有3个吃人的魔鬼和3个传教士,有一条船,最多可以载2人过河,划船至少有1人,如图111.jpg所示。游戏规则是,无论在右岸还是左岸,只要魔鬼数大于传教士数,传教士将会被吃掉。问题是,采用什么样的过河方法,才能使得魔鬼与传教士相安无事? On the right bank of the river there are three man-eating demons and three missionaries, and there is a boat that can carry up to two people across the river and row at least one person, as shown in FIG. 111.jpg. The rule of the game is that on either the right or the left bank, as long as the devil number is greater than the missionary number, the missionary will be eaten. The question was, what method of crossing the river would make the devil and the missionary at peace?
