Perhaps you should try some spelling variations:
"modified adaptive quantization algorithm" » "modified adaptive estimation algorithm", "modified adaptive ventilation algorithm", "modified passive quantization algorithm"
"modified adam estimation algorithms" » "modified adam estimation algorithm", "modified adam optimization algorithms", "modified adam optimisation algorithm", "modified df estimation algorithms", "modified near estimation algorithms"

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

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