Perhaps you should try some spelling variations:
"modified a estimation algorithm" » "modified _ estimation algorithm", "modified a destination algorithm", "modified _ estimating algorithm", "modified df estimation algorithm", "modified adam estimation algorithm"
"modified adamdamdamdaptive quantization algorithm" » "modified _damdamdamdaptive quantization algorithm", "modified dfdamdamdamdaptive quantization algorithm", "modified adamdamdamdamdaptive quantization algorithm"

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 adamdamdamdaptive quantization algorithm") or ("modified a estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adamdamdamdaptive quantization algorithm") OR ("modified a estimation algorithm")).
• Removing quotes may allow a broader search: (( modified adamdamdamdaptive quantization algorithm ) or ( modified a estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified adamdamdamdaptive quantization algorithm") or ("modified a estimation algorithm"))*.
