从上面的算法过程我们可以看到,求解同一个问题,branch and cut只用了3步,而branch and bound却用了4步。 There are many methods to solve the mixed-integer linear programming. Gomory Cutting Planes is fast, but unreliable. Branch and Bound is reliable but slow. The Branch and cut combine the advant...

Great progress was made in the late 1970s and 1980, when Grötschel, Padberg, Rinaldi and others managed to exactly solve instances with up to 2392 cities, using cutting planes and branch-and-bound. In the 1990s, Applegate, Bixby, Chvátal, and Cook developed the program Concorde that has...
branch and cut其实还是和branch and bound脱离不了干系的。所以,在开始本节的学习之前,请大家还是要务必掌握branch and bound算法的原理 。 01 应用背景 Branch and cut is a method of combinatorial optimization for solving integer linear programs (ILPs), that is, linear programming (LP) problems where ...

so that some instances with tens of thousands of cities can be solved. The TSP has several applications even in its purest formulation, such as planning, logistics, and the manufacture of microchips. Slightly modified, it appears as a sub-problem in many areas, such as DNA sequencing. In th...
