Perhaps you should try some spelling variations:
"modified objective optimized algorithmss" » "modified objective optimized algorithms", "modified objective optimized algorithm", "modified objective optimizer algorithms", "modified objective optimal algorithmss", "modified objective optimization algorithmss"
"modified choosing optimizer algorithm" » "modified choosing optimizer algorithms", "modified choosing optimized algorithm", "modified choosing optimized algorithms", "modified caging optimizer 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 choosing optimizer algorithm") OR ("modified objective optimized algorithmss"))~.
• Removing quotes may allow a broader search: (( modified choosing optimizer algorithm ) or ( modified objective optimized algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified choosing optimizer algorithm") or ("modified objective optimized algorithmss"))*.
