Perhaps you should try some spelling variations:
metaheuristicas » metaheuristics (Expand Search), metaheuristicos (Expand Search), metaheuristic (Expand Search), metaheuristicaas (Expand Search), metaheuristicasas (Expand Search)
algorithm » algoritmo (Expand Search)
algorithms » algoritmos (Expand Search), algoritmo (Expand Search)
metaheuristica » metaheuristicaa (Expand Search), metaheuristicasa (Expand Search)
metaheuristicosa » metaheuristicaosa (Expand Search), metaheuristicasosa (Expand Search)
heuristic » heuristica (Expand Search), heuristicas (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: ((((metaheuristica OR metaheuristicosa) OR metaheuristicas) algorithm) OR (heuristic algorithms)).
