Perhaps you should try some spelling variations:
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithm"
"modified male optimization algorithm" » "modified male optimization algorithms", "modified male optimisation algorithm", "modified male estimation algorithm", "modified game optimization algorithm", "modified market optimization algorithm", "modified stage optimization algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified objective optimization algorithm") OR ("modified male optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimization algorithm\") OR (\"modified male optimization algorithm\"))".
• Removing quotes may allow a broader search: (( modified objective optimization algorithm ) OR ( modified male optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithm") OR ("modified male optimization algorithm"))*.
