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

Try widening your search to All Fields.

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

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