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