A Branch and Price Algorithm for a Stackelberg Security Game

WebBranch and price is a generalization of linear programming (LP) based branch and bound specifically designed to handle integer programming (IP) formulations that contain a huge number of variables. The basic idea of branch and price is simple. Columns are left out of the LP relaxation because there are too many columns to handle efficiently and most of … WebThe algorithms used to solve these games find optimal randomized schedules to allocate security resources for infrastructure protection. Unfortunately, the state of the art algorithms either fail to scale or to provide a correct solution for large problems with arbitrary scheduling constraints.
