Perhaps you should try some spelling variations:
"modified adaptive quantization algorithm" » "modified adaptive estimation algorithm", "modified adaptive ventilation algorithm", "modified passive quantization algorithm"
"modified learning convolution algorithm" » "modified learning convolution algorithms", "modified learning evolution algorithm", "modified learning solution algorithm", "mobile learning convolution algorithm", "modified caging convolution algorithm"

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

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