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 estimation algorithms" » "modified quantile estimation algorithm", "modified quantile optimization algorithms", "modified quantile optimisation algorithm"

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 adaptive convolution algorithms") OR ("modified quantile estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified adaptive convolution algorithms ) or ( modified quantile estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive convolution algorithms") or ("modified quantile estimation algorithms"))*.
