Branch and bound research methodThe purpose of this chapter is to introduce and illustrate the most popular and successful computational approach to integer programming problems today. Rather than being a specific algorithm, branch and bound is a general principle that allows the user to finetune ...
Stochastic integer programming problems under probabilistic constraints are considered. Deterministic equivalent formulations of the original problem are obtained by using p-efficient points of the distribution function of the right hand side vector. A branch and bound solution method is proposed based on ...
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...
具有二次约束的MIP模型称为混合整数二次约束规划(Mixed Integer Quadratically Constrained Programming, MIQCP)问题。没有任何二次特征的模型通常被称为混合整数线性规划(MILP)问题。以下是Gurobi用于解决MILP模型的算法的描述, MIQP和MIQCP与此类似。 二Branch-and-Bound MILP问题一般用基于Branch-and-Bound算法的线性规...
