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