Perhaps you should try some spelling variations:
"modified _daptive quantization algorithm" » "modified _daptive estimation algorithm", "modified adaptive quantization algorithm", "modified adaptive ventilation algorithm", "modified passive quantization algorithm"
"modified adam convolution algorithms" » "modified adam evolution algorithm", "modified adam solution algorithm", "modified df convolution algorithms", "modified near convolution 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 _daptive quantization algorithm") or ("modified adam convolution algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified _daptive quantization algorithm") OR ("modified adam convolution algorithms")).
• Removing quotes may allow a broader search: (( modified _daptive quantization algorithm ) or ( modified adam convolution algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified _daptive quantization algorithm") or ("modified adam convolution algorithms"))*.
