Perhaps you should try some spelling variations:
"modified trace convolution algorithms" » "modified trace evolution algorithm", "modified trace solution algorithm", "modified trained convolutional algorithms", "modified traces convolution algorithms", "modified male convolution algorithms", "modified orca 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.

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