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 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified charging convolution algorithms\") OR (\"modified adaptive quantization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified charging convolution algorithms ) OR ( modified adaptive quantization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified charging convolution algorithms") OR ("modified adaptive quantization algorithm"))*.
