Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"modified df evaluation algorithm" » "modified df evolution algorithm", "modified df estimation algorithm", "modified df solution algorithm", "modified _ evaluation algorithm", "modified a valuation algorithm", "modified study evaluation algorithm", "modified adam evaluation algorithm", "modified bi1 evaluation algorithm"

Try widening your search to All Fields.

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 optimized algorithms") or ("modified df evaluation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimized algorithms") OR ("modified df evaluation algorithm")).
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithms ) or ( modified df evaluation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimized algorithms") or ("modified df evaluation algorithm"))*.
