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