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