Perhaps you should try some spelling variations:
"modified notion estimation algorithmssss" » "modified notion estimation algorithms", "modified notion estimation algorithm", "modified motion estimation algorithmssss"
"modified policy optimization algorithms" » "modified policy optimisation algorithm", "modified policy estimation algorithms", "modified policy estimation algorithm", "modified topology optimization algorithms"

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