Perhaps you should try some spelling variations:
metaheuristicaa » metaheuristicas (Expand Search), metaheuristics (Expand Search), metaheuristic (Expand Search), metaheuristicaaa (Expand Search), metaheuristicasaa (Expand Search)
algorithm » algoritmo (Expand Search)
algorithms » algoritmos (Expand Search)
metaheuristica » metaheuristicaa (Expand Search), metaheuristicasa (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: (((metaheuristica OR metaheuristicaa) algorithm) OR ((heuristic OR heuristicasa) algorithms)).
