跳马的回溯算法（8*8 的国际象棋棋盘上的一只马，恰好走过除起点外的其它63 个位置各一次，最后回 到起点。这条路线称为一条马的Hamilton 周游路线。对于给定的m*n 的国际象棋棋盘，m和n均为大于5 的偶数，且|m-n|≤2，该算法找出一条马的Hamilton周游路线。--Vault of the backtracking algorithm (8* 8 chess board on a horse, just walk outside except from the other 63 locations each time, finally returned to the starting point. This line is called a horse' s Hamilton traveled routes. For the a given m* n chess board, m and n are greater than 5, even, and | mn | ≤ 2, the algorithm is to find a horse' s Hamilton traveled routes.--
