β¦ Synopsis
We establish a necessary and su cient condition for a greedy algorithm to ΓΏnd an optimal solution in the case of integer programs with separable concave objective functions. This extends some well-known results for spanning trees, matroids, and greedoids. As a corollary we obtain one new generalization of matroids and integer polymatroids preserving the optimality of greedy solutions. ?

Six greedy primal selection rules are evaluated on a class of generalized set packing models. The evaluation is conducted in accordance with experimental design methodologies proposed by Lin and Rardin. Results indicate that the simplest of rules performs best, except when the model constraints exhi
