Perhaps you should try some spelling variations:
"modified adam approximation algorithm" » "modified adam approximation algorithms", "modified _ approximation algorithm", "modified one approximation algorithm", "modified time approximation algorithm", "modified df approximation algorithm", "modified near approximation algorithm"
"modified adaptive convolution algorithms" » "modified adaptive evolution algorithm", "modified adaptive solution algorithm", "modified adaptive construction algorithms", "modified adaptive ventilation algorithms", "modified passive convolution algorithms"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adam approximation algorithm") OR ("modified adaptive convolution algorithms"))~.
• Removing quotes may allow a broader search: (( modified adam approximation algorithm ) or ( modified adaptive convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adam approximation algorithm") or ("modified adaptive convolution algorithms"))*.
