Perhaps you should try some spelling variations:
"modified via convolution algorithms" » "modified via evolution algorithm", "modified via solution algorithm", "modified bi1 convolution algorithms", "modified adam convolution algorithms", "modified near convolution algorithms"
"modified dfdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified dfdaptive estimation 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 via convolution algorithms\") OR (\"modified dfdaptive quantization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified via convolution algorithms ) OR ( modified dfdaptive quantization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified via convolution algorithms") OR ("modified dfdaptive quantization algorithm"))*.
