WebThe tolerance for the optimization: if the updates are smaller than tol, the optimization code checks the dual gap for optimality and continues until it is smaller than tol. Additionally, when the model does not converge, we can get: ConvergenceWarning: Objective did not converge. You might want to increase the number of iterations. WebOct 10, 2024 · What I mean by saying "traditional" is that I solve the master problem (MP) to optimality where the optimal provides an upper bound (UP). Then, a Benders cut (feasibility of optimality) is generated from the subproblem (SP) and a lower bound (LB) is obtained (not necessarily improved at every iteration). The MP is updated with the Benders cut. how to say i love you grandma in spanish
