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