Abstract:

An algorithm is presented for solving general forest planning models when spatial relationships, in particular adjacent constraints, are considered. We solve a master linear program with a column generation approach. The generation of columns is done by solving a stable set problem. To preserve the adjacency properties, fractional solutions in the master problem are rounded off to integrality through a heuristic procedure. Computational experience on medium-sized problems showed that solutions with small deviations from the optimal could be obtained with moderate computational effort. For. Sci. 40(1):142-161.
