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