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