Perhaps you should try some spelling variations:
"modified bi1damdamdaptive quantization algorithm" » "modified bi1damdamdaptive estimation algorithm"
"modified df approximation algorithms" » "modified _ approximation algorithms", "modified one approximation algorithms", "modified time approximation algorithms", "modified adam approximation algorithms", "modified bi1 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 df approximation algorithms") or ("modified bi1damdamdaptive quantization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified df approximation algorithms") OR ("modified bi1damdamdaptive quantization algorithm")).
• Removing quotes may allow a broader search: (( modified df approximation algorithms ) or ( modified bi1damdamdaptive quantization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified df approximation algorithms") or ("modified bi1damdamdaptive quantization algorithm"))*.
