在线性规划的实际问题中,往往需求最优整数解,课本中也出现了这样的例题和习题,但课本回避了如何求最优整数解这个问题,以致学生在遇到最优整数解不只一个或最优整数解不在边界折线顶点附近的问题时,不是错解就 In the practical problems of linear programming, the optimal integer solution is often required. Such examples and exercises are also found in textbooks. However, the textbook avoids the problem of how to find the optimal integer solution, so that students encounter more than one optimal integer solution. Or the problem that the optimal integer solution is not near the vertex of the boundary polyline is not an error solution.
