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