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