Benders Cuts in Branch and Bound Tree
AnsweredHello, I am solving a two stage stochastic model in which the first stage has integer variables. I am using the Benders cuts and adding them to the MIP nodes of the branch and bound tree. This is t...

Cut Generation LP ( CGLP)
AnsweredHi, I am writing an algorithm in which after solving LP relaxation of several sub-problems from a two-stage stochastic model. I want to use CGLP to generate disjunctive cuts. To generate disjunctiv...
