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