Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"modified time evaluation algorithm" » "modified time evolution algorithm", "modified time estimation algorithm", "modified time solution algorithm", "modified based evaluation algorithm", "modified large evaluation algorithm", "modified bi1 evaluation algorithm", "modified male 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 optimization algorithm") or ("modified time evaluation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimization algorithm") OR ("modified time evaluation algorithm")).
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithm ) or ( modified time evaluation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithm") or ("modified time evaluation algorithm"))*.
