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 estimation algorithms" » "modified trace estimation algorithm", "modified trace optimization algorithms", "modified trace optimisation algorithm", "modified pose estimation algorithms", "modified risk estimation algorithms", "modified traces estimation algorithms", "modified male estimation algorithms", "modified orca estimation 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 adaptive quantization algorithm\") OR (\"modified trace estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified adaptive quantization algorithm ) OR ( modified trace estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive quantization algorithm") OR ("modified trace estimation algorithms"))*.
