Perhaps you should try some spelling variations:
"modified adaptive estimation algorithm" » "modified adaptive ventilation algorithm", "modified quantile estimation algorithm", "modified adaptive quantization algorithm", "modified passive estimation algorithm"
"modified adam approximation algorithms" » "modified _ approximation algorithms", "modified one approximation algorithms", "modified time approximation algorithms", "modified df approximation algorithms", "modified near approximation algorithms"

Try widening your search to All Fields.

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

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