Perhaps you should try some spelling variations:
"enabling learning evolution algorithm" » "enabling learning evolutionary algorithm", "enabling learning convolution algorithms", "enabling learning estimation algorithm", "enabling learning convolution algorithm", "enabling learning emotion algorithm", "mapping learning evolution algorithm"
"modified objective solution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective convolution algorithms", "modified objective estimation 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 evolution algorithm") or ("modified objective solution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("enabling learning evolution algorithm") OR ("modified objective solution algorithm")).
• Removing quotes may allow a broader search: (( enabling learning evolution algorithm ) or ( modified objective solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("enabling learning evolution algorithm") or ("modified objective solution algorithm"))*.
