On the Hop Constrained Steiner Tree Problem with Multiple Root Nodeso improve the quality of lower bounds of both models. To solve the problem to optimality, we implement branch-and-price algorithms for all proposed formulations. Our computational results show that the branch-and-price approaches based on path formulations outperform the flow formulations if the hop limit is not too loose.

1.12 Programs for computational chemistry,. We demonstrate this by computing the bound associated with the level 1, 2, and 3 relaxations of several highly symmetric binary integer programming problems. We also present a class of constraints, called ., that further improves the bound, and in some cases provides a tight formulation.
