传教士与野人问题我们分两种情况考虑。先考虑船在左岸的情况。如果不考虑限制条件,也就是说,船一次可以将三人从左岸运到右岸,然后再有一个人将船送回来。这样,船一个来回可以运过河2人,而船仍然在左岸。而最后剩下的三个人,则可以一次将他们全部从左岸运到右岸。所以,在不考虑限制条件的情况下,也至少需要摆渡[(M+N-3)/2]*2+1次。其中分子上的"-3"表示剩下三个留待最后一次运过去。除以"2"是因为一个来回可以运过去2人,需要[(M+N-3)/2]个来回,而"来回"数不能是小数,需要向上取整,这个用符号[ ]表示。而乘以"2"是因为一个来回相当于两次摆渡,所以要乘以2。而最后的"+1",则表示将剩下的3个运过去,需要一次摆渡。-M-C products

Autonomous indoor mobile robots are gaining increasing popularity for the shared use in military
and civil applications. Recently aerial or ground robots of various shapes and sizes have been
developed for quick detection and observation of circumstances in calamity environments such as
indoor fire spots [1, 2]. In an indoor environment, however, weak reception of GPS signals has posed
additional challenges to the operation of the robots. Therefore less expensive self-localization with
unaided external sensors is one of the most important problems in popularizing indoor mobile robot
products.
