We present benchmarking results for a Ccode implementation of the proposed BB‐ASIPM solver, including a branch‐and‐bound(B&B) method with the proposed tailored presolve techniques and an active‐set based interior point method(ASIPM), compared against multiple state‐of‐the‐art MIQP solvers...
We present a branch and bound algorithm especially designed to efficiently target small instances up to 15 customers and a heuristic algorithm, using the branch and bound as a subroutine, to attack larger instances. Extensive experimental results suggest the effectiveness of the exact solver for small...
By combining the mature theory of the B-spline and the widely used branch-and-bound framework a novel spatial branch-and-bound (sBB) method is obtained. The method solves nonconvex mixed-integer nonlinear programming (MINLP) problems with spline constraints to global optimality. A broad ...
We will introduce our strategy for deleting points in the Hash table timely in Section 3.1, a new data structure for storing Small-DAG in Section 3.2, and a branch and bound method for deleting no-contributed points and non-longest paths in Section 3.3. Time and space complexity The time ...

In this paper,we introduce some simple cost based domain,ltering techniques [13].We test them on a branch-and-bound algorithm proposed by Carraghan and Parda-los [9].Their algorithm is still believed to be one of the fastest clique solver for sparse graphs. It recursively enlarges a clique...
A convenient approach to solving combinatorial optimization tasks in the form of Mixed Integer Linear Programs is Branch-and-Bound. Branch-and-Bound solver splits a task into two parts dividing the domain of an integer variable, then it solves them recursively, producing a tree of nested sub-...
