Perhaps you should try some spelling variations:
"modified adaptive quantization algorithm" » "modified adaptive estimation algorithm", "modified adaptive ventilation algorithm", "modified passive quantization algorithm"
"modified quantile approximation algorithms" » "modified time approximation algorithms", "modified diophantine approximation algorithms"

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

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