evolutionary algorithms [9] and enumerative schemes, both LP [7, 31] and non-LP based [20, 29]. However, for CSP where the right-hand side is large, LP-based exact methods have been more effective. In the last years many efforts have been successful to solve CSP exactly by an...
• COIN/BCP is focused on the implementation of ful l-blown branch( cut)and price algorithms. •The framework centers around the management of classes of dynamical ly generated cut and variables, generical ly cal led objects. • Subproblems are composed of dynamic l ists of these objects...
Branch-and-cut and Branch-and-Cut-and-Price Algorithms for Solving Vehicle Routing Problems This paper presents a branch-and-cut-and-price algorithm for the vehicle routing problem with time windows. The standard Dantzig-Wolfe decomposition of the arc flow formulation leads to a set partitioning ...
The experiments compare the new algorithms among themselves and also against the best algorithms currently available in the literature. As an outcome of them, one of the new algorithms stands out on top. 展开 关键词: Degree Constrained Spanning Tree Branch-and-cut Branch-and-cut-and-price ...
In particular, they devised exact and heuristic algorithms. The tests were run on 64 small instances, with 15 customers and up to three commodities, 80 mid-size instances with 20, 40, 60, or 80 customers and up to three commodities, and large instances with 100 customers. One of the ...
Finally, we compare our BPC algorithm with algorithms from the literature in Section 3.4. We Conclusions In this work, we have presented a new branch-price-and-cut (BPC) algorithm for the solution of different variants of the capacitated multiple vehicle traveling purchaser problem (MVTPP) with...
a novel feature is introduced in such kind of algorithms: powerful new cuts expressed over a very large set of variables are added, without increasing the complexity of the pricing subproblem or the size of the LPs that are actually solved. Computational results on benchmark instances from the ...
