Perhaps you should try some spelling variations:
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one approximation algorithms"
"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: (("modified notion approximation algorithms") OR ("mobile learning predation algorithm"))~.
• Removing quotes may allow a broader search: (( modified notion approximation algorithms ) or ( mobile learning predation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified notion approximation algorithms") or ("mobile learning predation algorithm"))*.
