Perhaps you should try some spelling variations:
"modified charging convolution algorithms" » "modified charging evolution algorithm", "modified charging solution algorithm", "modified learning convolution algorithms", "modified caging convolution algorithms", "modified carbon convolution algorithms"
"modified passive quantization algorithm" » "modified passive estimation algorithm", "modified adaptive 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 charging convolution algorithms") OR ("modified passive quantization algorithm"))~.
• Removing quotes may allow a broader search: (( modified charging convolution algorithms ) or ( modified passive quantization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified charging convolution algorithms") or ("modified passive quantization algorithm"))*.
