Perhaps you should try some spelling variations:
"modified charging convolution algorithms" » "modified charging evolution algorithm", "modified charging solution algorithm", "modified learning convolution algorithms", "modified caging convolution algorithms", "modified carbon convolution algorithms"
"modified quantile estimation algorithm" » "modified adaptive estimation 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 charging convolution algorithms") OR ("modified quantile estimation algorithm"))~.
• Removing quotes may allow a broader search: (( modified charging convolution algorithms ) or ( modified quantile estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified charging convolution algorithms") or ("modified quantile estimation algorithm"))*.
