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