Perhaps you should try some spelling variations:
"modified parameter optimization algorithms" » "modified parameter optimisation algorithm", "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameters optimization algorithms"
"modified objective optimizer algorithmssss" » "modified objective optimizer algorithms", "modified objective optimized algorithms", "modified objective optimized algorithm", "modified objective optimal algorithmssss", "modified objective optimization algorithmssss"

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 algorithms") OR ("modified objective optimizer algorithmssss"))~.
• Removing quotes may allow a broader search: (( modified parameter optimization algorithms ) or ( modified objective optimizer algorithmssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimization algorithms") or ("modified objective optimizer algorithmssss"))*.
