WebApr 16, 2024 · A branch-and-cut algorithm for MIBLP. Our solution algorithm for MIBLP relies on the solution of the bilinear relaxation (1), (2), (3), (3), in which nonlinear constraints (5) are initially removed. To this end, an effective branch-and-cut MILP solver is used, which computes an optimal solution of the Linear Programming (LP) relaxation (1), (2 ...
