Perhaps you should try some spelling variations:
"modified adaptive quantization algorithm" » "modified adaptive estimation algorithm", "modified adaptive ventilation algorithm", "modified passive quantization algorithm"
"modified trace approximation algorithms" » "modified time approximation algorithms", "modified average approximation algorithms", "modified one approximation algorithms", "modified traces approximation algorithms", "modified male approximation algorithms", "modified orca approximation algorithms"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified trace approximation algorithms") OR ("modified adaptive quantization algorithm"))~.
• Removing quotes may allow a broader search: (( modified trace approximation algorithms ) or ( modified adaptive quantization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified trace approximation algorithms") or ("modified adaptive quantization algorithm"))*.
