WebMar 24, 2024 · Branch and bound algorithms are a variety of adaptive partition strategies have been proposed to solve global optimization models. These are based upon partition, sampling, and subsequent lower and upper bounding procedures: these operations are applied iteratively to the collection of active ("candidate") subsets within the feasible set D. WebThe branch and bound algorithm is a widely used method for solving integer programming problems. It involves solving a sequence of linear programming (LP) relaxations of the original problem, where the integrality constraints are relaxed.
