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

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 nodal convolution algorithms"))~.
• Removing quotes may allow a broader search: (( modified adaptive quantization algorithm ) or ( modified nodal convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive quantization algorithm") or ("modified nodal convolution algorithms"))*.
