Branch and bound is a useful problem solving technique. The idea is, if you have a minimization problem you want to solve, maybe there is a way to relax the constraints to an easier problem. If so, the solution of the easier problem is a lower bound on the possible solution of the hard problem. … Continue reading A Basic Branch and Bound Solver in Python using Cvxpy Using a custom timer class, the following is a program which reduces the problem of selecting which Debian Linux packages to include on installation media, to the classical knapsack problem. This program implements an exhaustive search algorithm for this problem, and displays its performance running time to the screen.
