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 charging estimation algorithm" » "modified charging station algorithm", "modified caging estimation algorithm", "modified carbon 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 estimation algorithm") OR ("modified adaptive convolution algorithms"))~.
• Removing quotes may allow a broader search: (( modified charging estimation algorithm ) or ( modified adaptive convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified charging estimation algorithm") or ("modified adaptive convolution algorithms"))*.
