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

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

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