Perhaps you should try some spelling variations:
"modified adaptive quantization algorithm" » "modified adaptive estimation algorithm", "modified adaptive ventilation algorithm", "modified passive quantization algorithm"
"modified adaptive optimized algorithm" » "modified adaptive optimized algorithms", "modified adaptive optimizer algorithms", "modified passive optimized algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified adaptive quantization algorithm") OR ("modified adaptive optimized algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adaptive quantization algorithm\") OR (\"modified adaptive optimized algorithm\"))*".
• Removing quotes may allow a broader search: (( modified adaptive quantization algorithm ) OR ( modified adaptive optimized algorithm ))*.
