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