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