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