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