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