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