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 df optimizer algorithms" » "modified df optimized algorithms", "modified df optimized algorithm", "modified df optimization algorithms", "modified _ optimized algorithms", "modified _ optimize algorithms", "modified _ optimizer algorithms", "modified adam optimizer algorithms", "modified bi1 optimizer 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 df optimizer algorithms") or ("modified notion estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified df optimizer algorithms") OR ("modified notion estimation algorithms")).
• Removing quotes may allow a broader search: (( modified df optimizer algorithms ) or ( modified notion estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified df optimizer algorithms") or ("modified notion estimation algorithms"))*.
