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