For its exact solution, we propose a branch-price-and-cut algorithm that employs and tailors stabilization techniques that have been successfully applied to several cutting and packing problems. More precisely, we make use of (deep) dual-optimal inequalities which are particularly suited to reduce ...
When the relaxation in each node of a branch-and- bound tree is solved by column generation, one speaks of branch-and-price. Optionally, cutting planes can be added in order to strengthen the relaxation, and this is called branch- price-and-cut. We introduce the common concepts of ...
When the relaxation in each node of a branch-andbound tree is solved by column generation, one speaks of branch-and-price. Optionally, cutting planes can be added in order to strengthen the relaxation, and this is called branchprice-and-cut. We introduce the common concepts of convexification...
(2021) present a branch-price-and-cut algorithm for the solution of different variants of the multi-vehicle TPP with unitary demands. In the IRPs commodities need to be explicitly considered when at least one of the following conditions applies: commodities are associated with different production ...
因为branch and price算法就是branch and bound和column generation的结合体。 2 应用背景 branch and price算法就是branch and bound和column generation的结合体。具体是怎么结合的呢?先看一张BP的算法流程图,相信大家会清晰很多: 3 具体流程 我们知道branch and bound求解整数规划的过程,如果不知道看看下面这张图回...
