Perhaps you should try some spelling variations:
"modified multiobjective optimisation algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithm", "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective estimation algorithms"
"modified male optimization algorithm" » "modified male optimization algorithms", "modified male estimation algorithm", "modified male estimation algorithms", "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 multiobjective optimisation algorithm") OR ("modified male optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimisation algorithm\") OR (\"modified male optimization algorithm\"))".
• Removing quotes may allow a broader search: (( modified multiobjective optimisation algorithm ) OR ( modified male optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimisation algorithm") OR ("modified male optimization algorithm"))*.
