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