Branch and cut involves running a branch and bound algorithm and using cutting planes to tighten the linear programming relaxations. Note that if cuts are only used to tighten the initial LP relaxation, the alg
The inequalities and separation procedures are used in a branch-and-cut algorithm. Computational experiments on a large set of generated test instances show that both the valid inequalities and the new separation procedures significantly improve the performance of the branch-and-cut algorithm....

In Section 4, we present a reformulation based on a directed graph and we adapt several properties of the problem and some valid inequalities to this formulation to obtain a hybrid formulation. The branch-and-cut algorithm is described in Section 5. Comparative computational results and conclusions...

We give integer programming formulations and valid inequalities for the different versions of the problem, solve them using a branch-and-cut algorithm, and discuss computational results. Some of the new inequalities can be used also to solve other problems in the literature, like the plant cycle ...
