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