Perhaps you should try some spelling variations:
"modified objective optimized algorithms" » "modified objective optimizer algorithms", "modified objective optimization algorithms", "modified objective optimal algorithms", "modified objective optimizer algorithmss"
"modified caging optimized algorithm" » "modified caging optimizer algorithms", "modified aging optimized algorithm", "modified changing optimized algorithm", "modified charging optimized algorithm"

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 objective optimized algorithms") OR ("modified caging optimized algorithm"))~.
• Removing quotes may allow a broader search: (( modified objective optimized algorithms ) or ( modified caging optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimized algorithms") or ("modified caging optimized algorithm"))*.
