一、问题提出
3 名商人带 3 名随从乘一条小船过河,小船每次只能承载至多两
人。随从们密约, 在河的任一
岸, 一旦随从的人数比商人多,
就杀人越货.乘船渡河的方案
由商人决定,商人们如何才能
安全渡河呢?
二、问题分析
商人与随从过河问题可以视为是一个多步决策的过程,通过多次
优化,从而得到一个全局最优的决策方案。决策的每一步,即船从此
岸到达彼岸,都要对船上的商人和仆人数做出决策。在保证河的任一
岸均有商人数比随从人数多和小船每次最多只能承载两人的前提下,
经有限步使所有人员到达彼岸。
三、模型假设
商人和随从都会划船,天气很好,无大风大浪,且船的质量很好,
可以保证很多次安全的运载商人和随从。
四、模型建立
