Perhaps you should try some spelling variations:
"modified learning method algorithm" » "mobile learning method algorithm", "modified caging method algorithm", "modified learning mom algorithm", "modified learning methods algorithm", "modified graining methods algorithm", "modified learning emotion algorithm"
"modified one approximation algorithms" » "modified time approximation algorithms", "modified _ approximation algorithms", "modified rough approximations algorithms", "modified male approximation algorithms", "modified near approximation algorithms", "modified orca approximation algorithms"

You may be able to get more results by adjusting your search query.

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