Perhaps you should try some spelling variations:
"modified _daptive quantization algorithm" » "modified _daptive estimation algorithm", "modified adaptive quantization algorithm", "modified adaptive ventilation algorithm", "modified passive quantization algorithm"
"modified one approximation algorithms" » "modified time approximation algorithms", "modified _ approximation algorithms", "modified rough approximations algorithms", "modified male approximation algorithms", "modified near approximation algorithms", "modified orca approximation algorithms"

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 _daptive quantization algorithm\") OR (\"modified one approximation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified _daptive quantization algorithm ) OR ( modified one approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified _daptive quantization algorithm") OR ("modified one approximation algorithms"))*.
