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 response estimation algorithms" » "modified response estimation algorithm", "modified response optimization algorithms", "modified response optimisation algorithm", "modified pose estimation algorithms", "modified response association 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 response estimation algorithms") OR ("modified adam approximation algorithm"))~.
• Removing quotes may allow a broader search: (( modified response estimation algorithms ) or ( modified adam approximation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified response estimation algorithms") or ("modified adam approximation algorithm"))*.
