To fill in this gap, we propose an enhanced branch-and-bound algorithm for bilevel integer linear programming (BILP) problems where decision variables are all integers. We take a branching rule previously proposed by Xu and Wang (2014) as the benchmark and embed an enhanced branching idea in...
运筹我们最先接触分支定界算法,也就是由Land Doig和Dakin在20实世纪60年代初提出的branch and bound算法,用在整数规划(Integer Programming,简称IP。全部决策变量是整数)中。其实用在混合整数规划(部分决策变量是整数)中也是可以的(本身混合整数规划就能够转化为整数规划)。 目前很多求解器,如cplex和gurobi就是基于分...

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...

This problem is formulated as a mixed integer programme, and a branch and bound algorithm is presented for its solution. The structural properties of this programming problem are discussed, which con be used to improve the computational efficiency of our branch and bound algorithm. An illustrative ...
IntegerProgrammingThis paper describes a branch and bound algorithm for a general class of asymmetrical vehicle routeing problems. Vehicle routes start and end at a central depot. Visits are made to nodes grouped into clusters: every cluster must receive a minimum number of visits. But not all ...
