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