Perhaps you should try some spelling variations:
"modified network approximation algorithms" » "certified network approximation algorithms", "defined network approximation algorithms", "modified near approximation 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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified network approximation algorithms") or ("mobile learning method algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified network approximation algorithms") OR ("mobile learning method algorithm")).
• Removing quotes may allow a broader search: (( modified network approximation algorithms ) or ( mobile learning method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified network approximation algorithms") or ("mobile learning method algorithm"))*.
