Perhaps you should try some spelling variations:
"modified dfdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified dfdaptive estimation algorithm", "modified _daptive quantization algorithm", "modified adamdaptive quantization algorithm", "modified bi1daptive quantization algorithm"
"modified df convolution algorithms" » "modified df evolution algorithm", "modified df solution algorithm", "modified d convolutional algorithms", "modified _ convolution algorithms", "modified adam convolution algorithms", "modified bi1 convolution algorithms"

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 dfdaptive quantization algorithm\") OR (\"modified df convolution algorithms\"))~".
• Removing quotes may allow a broader search: (( modified dfdaptive quantization algorithm ) OR ( modified df convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified dfdaptive quantization algorithm") OR ("modified df convolution algorithms"))*.
