Perhaps you should try some spelling variations:
"modified policy optimization algorithm" » "modified policy optimization algorithms", "modified policy optimisation algorithm", "modified policy estimation algorithm", "modified topology optimization algorithm"
"modified parameters estimation algorithms" » "modified parameter estimation algorithms", "modified parameter estimates algorithms", "modified parameter optimization algorithms", "modified parameters estimation algorithm", "modified parameters optimization algorithms", "modified parameters optimisation algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified parameters estimation algorithms") or ("modified policy optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameters estimation algorithms") OR ("modified policy optimization algorithm")).
• Removing quotes may allow a broader search: (( modified parameters estimation algorithms ) or ( modified policy optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters estimation algorithms") or ("modified policy optimization algorithm"))*.
