【摘要】 通过两个组合最优化问题的实例，我们发现某类组合最优化问题能用舍入法求解．也就是说首先求解组合最优化问题的连续模型，然后巧妙舍入连续最优解，得到原问题最优解．更多还原

【Abstract】 By discussing two practical examples of combinatory optimum problems, we have found that some of the combinatory optimum problems can be solved by rounding-off method. That is, we get the optimum solution by resolving its cont1nuous model firstly. Then we can get the optimum solution of the original discontinuous problem,by rounding the solution ingenlously.更多还原
