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