Perhaps you should try some spelling variations:
"modified dffdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified dffdaptive estimation algorithm"
"modified deep convolution algorithms" » "modified deep evolution algorithm", "modified deep solution algorithm", "modified deep convolutional algorithms", "modified delphi convolution algorithms", "modified df convolution algorithms", "modified near convolution algorithms"

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