说明：  用优化算法求解运输问题。 1.不使用linprog，比较歧异解 2.用西北角法求初始基本可行解，用闭回路法确定退出基和更新运输矩阵 3.不能处理非平衡的运输问题(Optimization algorithm used to solve transport problems. 1. Do not use linprog, compare differences solution 2. With the northwest corner of France seeking an initial basic feasible solution, using closed-loop method to determine the transport out of the base and update the matrix 3. Can not handle the transport of non-equilibrium)
