Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"modified male optimized algorithms" » "modified male optimized algorithm", "modified male optimizer algorithms", "modified male optimization algorithms", "modified made optimized algorithms", "modified make optimized algorithms"

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

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