Parametric Branch and Bound
The paper describes a procedure for mixed integer programming that allows branches to be imposed 'by degrees', which can subsequently be revised or weeded out according to their relative influence. It is an adaptive approach in which the branch and bound tree can be maillipulated and rl'Structured. The approach also yields measures of the costs of imposing the branches that lead to integer solu...
متن کاملBranch and Bound Methods
Branch and bound algorithms are methods for global optimization in nonconvex problems [LW66, Moo91]. They are nonheuristic, in the sense that they maintain a provable upper and lower bound on the (globally) optimal objective value; they terminate with a certificate proving that the suboptimal point found is ǫ-suboptimal. Branch and bound algorithms can be (and often are) slow, however. In the w...
متن کاملBranch-and-Bound and Beyond
The branch-and-bound algorithm is stated in general i ty, and i l l us t ra ted by two applications, unidirect ional graph search, and reducing a sparse matrix to i t s minimal band form. The algorithm is then generalised to mult iple par t i t ions , applied to bid i rect ional graph searching for both heurist ic and non-heuristic searches, and further extended to graph searches and problem so...
متن کاملVisualizing Branch-and-Bound Algorithms
We present a suite of tools for visualizing the status and progress of branch-and-bound algorithms for mixed integer programming. By integrating these tools with the open-source codes CBC, SYMPHONY, and GLPK, we demonstrate the potential usefulness of visual representations in helping a user predict future progress of the algorithm or analyzing the algorithm’s performance. We have also implemen...
متن کاملParallel Branch-and-Bound Algorithms
1.1. INTRODUCTION In the beginning of the twenty-first century, large unsolved combinatorial optimization problems have been solved exactly. Two impressive cases should be mentioned. First are two instances of the Monde, Transfert) newspapers. This impressive media frenzy reflected the impact of the achievement, which was deemed of the same order of magnitude as the victory of IBMs parallel com...
