Perhaps you should try some spelling variations:
metaheuristicass » metaheuristics (Expand Search), metaheuristica (Expand Search), metaheuristicos (Expand Search), metaheuristicaass (Expand Search), metaheuristicasass (Expand Search)
algorithm » algoritmo (Expand Search)
algorithms » algoritmos (Expand Search)
metaheuristicas » metaheuristicaas (Expand Search), metaheuristicasas (Expand Search)
heuristic » heuristica (Expand Search), heuristicas (Expand Search)
heuristicasa » heuristicaasa (Expand Search), heuristicasasa (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: (((metaheuristicas OR metaheuristicass) algorithm) OR ((heuristic OR heuristicasa) algorithms)).
