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