متن کاملSolving Connected Subgraph Problems in Wildlife Conservation
We investigate mathematical formulations and solution techniques for a variant of the Connected Subgraph Problem.

In this work we focus on the budget-constrained version, where we maximize the total profit of the nodes in the subgra...
