Perhaps you should try some spelling variations:
"modified notion estimation algorithms" » "modified notion estimation algorithm", "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified motion estimation algorithms"
"modified adam optimized algorithms" » "modified adam optimized algorithm", "modified adam optimizer algorithms", "modified adam optimization algorithms", "modified df optimized algorithms", "modified near optimized algorithms"

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

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