Perhaps you should try some spelling variations:
"enabling learning convolution algorithm" » "enabling learning convolution algorithms", "enabling learning evolution algorithm", "enabling learning solution algorithm", "mapping learning convolution algorithm"
"modified objective predation algorithm" » "modified objective allocation algorithm", "modified objective predators algorithm", "modified objective estimation algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("enabling learning convolution algorithm") or ("modified objective predation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("enabling learning convolution algorithm") OR ("modified objective predation algorithm")).
• Removing quotes may allow a broader search: (( enabling learning convolution algorithm ) or ( modified objective predation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("enabling learning convolution algorithm") or ("modified objective predation algorithm"))*.
