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