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