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