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