Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"mobile learning aided algorithm" » "machine learning aided algorithm", "mobile learning adam algorithm", "mobile learning driven algorithm", "mobile learning winner algorithm", "mobile learning based algorithm", "mobile learning model 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 aided algorithm") OR ("modified notion optimization algorithms"))~.
• Removing quotes may allow a broader search: (( mobile learning aided algorithm ) or ( modified notion optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("mobile learning aided algorithm") or ("modified notion optimization algorithms"))*.
