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