Abstract: The greedy randomized adaptive search procedure (GRASP) is a well-known computational procedure for handling combinatorial optimization problems. Hyperheuristics, or heuristics to choose heuristics, are higher-level ...

Abstract: When decentralized strategies are considered for managing wastewater, natural systems for wastewater treatment (NSWT) (constructed wetlands) seem to be strongly preferred in comparison with the conventional activated sludge ...
