Two problem formulations based on two, and three-index vehicle routing models are proposed and solved using a branch-and-cut procedure. Moreover, a logic-based branch-and-Benders-cut algorithm is developed. Computational experiments on real-world instances demonstrate that the proposed algorithm ...
Algorithm BCxy Here the integrality of some or all of the y-variables is treated by allowing branching on y-variables. However the linear programs that arise in solving the Master problem still only involve the x,η variables. At a given node of the branch-and-cut tree for the Benders Ma...
The 1-PDTSP and the SP belong to the class of the many-to-many routing problems ([11]), in which multiple supplies can serve multiple demands. The authors have proposed a branch-and-cut algorithmthat combines standard TSP constraints with Benders cuts, clique cuts and multistar inequalities ...

(6) We describe the learning process, train, and embed a support vector machine classification algorithm capable of identifying the appropriate cut generation function (AOF) to be applied at each stage during the branch-cut-and-Benders process. (6) The entire solution framework is outlined, ...
