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