Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"modified location optimizer algorithms" » "modified location optimized algorithms", "modified location optimized algorithm", "modified location optimization algorithms", "modified carbon optimizer algorithms"

You may be able to get more results by adjusting your search query.

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