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 allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation algorithm"

Try widening your search to All Fields.

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