现在用在大规模求解IP和MIP的精确算法,比如branch and price和branch and cut算法都是基于分支定界算法框架而设计的。 比如branch and price算法,是在基本的branch and bound的基础上,在求解子节点松弛问题的时候采用列生成的方法,一列一列的添加变量,让问题规模从小变大,而别的都没变。原始的基础的branch and bo...

分支定界思想可以被看作是解决整数规划(IP)和混合整数规划(MIP)问题最核心的算法思维。很多商业求解器(例如Cplex, Gurobi)等都以这种思想作为框架进行设计。分支定界是整数规划领域的基石,也是分支定价(branch and price)算法,分支定价切割(branch and pricce and cut)算法的基础。
Branch, cut, and price (BCP) is an LP-based branch and bound technique for solving large-scale discrete optimization problems (DOPs). In BCP, both cuts and variables can be generated dynamically throughout the search tree. The ability to handle constantly changing sets of cuts and variables ...
