说明：   巫魔世界是一个被墙所环绕的二维格子世界，相邻格子相通，洞穴在左下角。每一个格子可以包含agent或物体。考虑到格子世界的大小对于本次问题的讨论不具绝对的影响，因此设定格子世界的行和列均为N，因此在本实验中，巫魔世界是一个N*N的二维格子，将世界中格子以行和列的二元组标示，因此洞穴入口在[1,1]。本程序实现了一个巫魔世界小游戏。
(Umoja world is surrounded by a wall of two-dimensional lattice world, adjacent to the same lattice, holes in the bottom left corner. Each lattice can contain agent or object. Taking into account the lattice size of the world for this discussion does not have an absolute impact, so set the world lattice rows and columns are N, therefore in this experiment, Umoja is a world N* N of the two-dimensional lattice will be world of lattice rows and columns in the dual group marked, so the cave entrance in the [1,1]. This procedure implements a Umoja game world.)
