Perhaps you should try some spelling variations:
"Multi-objetivo solutionary algorithms" » "Multi-objetivo evolutionary algorithms" (Expand Search), "Multi-objetivo solutionary algorithm" (Expand Search), "Multi-objetivo solutionary algoritmo" (Expand Search)
"multi-objective evolution algorithms" » "multi-objective evolution algorithm" (Expand Search), "multi-objective evolution algoritmo" (Expand Search), "multi-objective solution algorithms" (Expand Search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"Multi-objetivo solutionary algorithms\") OR (\"multi-objective evolution algorithms\"))~".
• Removing quotes may allow a broader search: (( Multi-objetivo solutionary algorithms ) OR ( multi-objective evolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("Multi-objetivo solutionary algorithms") OR ("multi-objective evolution algorithms"))*.
