Perhaps you should try some spelling variations:
"modified dfdamdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified dfdamdaptive estimation algorithm", "modified _damdaptive quantization algorithm", "modified adamdamdaptive quantization algorithm", "modified bi1damdaptive quantization algorithm"
"modified df optimized algorithm" » "modified df optimized algorithms", "modified df optimizer algorithms", "modified _ optimized algorithm", "modified _ optimize algorithm", "modified adam optimized algorithm", "modified bi1 optimized 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 dfdamdaptive quantization algorithm\") OR (\"modified df optimized algorithm\"))~".
• Removing quotes may allow a broader search: (( modified dfdamdaptive quantization algorithm ) OR ( modified df optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified dfdamdaptive quantization algorithm") OR ("modified df optimized algorithm"))*.
