Perhaps you should try some spelling variations:
"modified quantile approximation algorithms" » "modified time approximation algorithms", "modified diophantine approximation algorithms"
"modified adaptive estimation algorithms" » "modified adaptive estimation algorithm", "modified adaptive optimization algorithms", "modified adaptive optimisation algorithm", "modified adaptive ventilation algorithms", "modified quantile estimation algorithms", "modified adaptive quantization algorithms", "modified passive 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 estimation algorithms\") OR (\"modified quantile approximation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified adaptive estimation algorithms ) OR ( modified quantile approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive estimation algorithms") OR ("modified quantile approximation algorithms"))*.
