This paper proposes a branch and bound method that solves a class of nonlinear integer programming problems. A separable convex objective function is minimized over a feasible region defined by the constraints

In this subsection, we first overview the general branch-and-bound algorithm and the two most crucial branching algorithms in branch-and-bound, including branching variable selection and node selection. Then, we introduce the cutting plane, which is part of the branch-and-cut method. Overview of...

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 ...
In our generalization we allow to take into account integer and continuous variables as well as an arbitrary weighting of the risk. In order to exactly solve our model, we propose a branch-and-bound method based on the computation of dual bounds via the solution of the primal relaxation. A...
branch and cut其实还是和branch and bound脱离不了干系的。所以,在开始本节的学习之前,请大家还是要务必掌握branch and bound算法的原理。 01 应用背景 Branch and cut is a method of combinatorial optimization for solving integer linear programs (ILPs), that is, linear programming (LP) problems where so...

To fill in this gap, we propose an enhanced branch-and-bound algorithm for bilevel integer linear programming (BILP) problems where decision variables are all integers. We take a branching rule previously proposed by Xu and Wang (2014) as the benchmark and embed an enhanced branching idea in...
