Perhaps you should try some spelling variations:
"machines learning method algorithm" » "machine learning method algorithm", "active learning method algorithm", "mapping learning method algorithm", "machines learning mom algorithm", "machines learning methods algorithm", "machines graining methods algorithm", "machines 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: (("machines learning method algorithm") or ("modified one approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machines learning method algorithm") OR ("modified one approximation algorithms")).
• Removing quotes may allow a broader search: (( machines learning method algorithm ) or ( modified one approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("machines learning method algorithm") or ("modified one approximation algorithms"))*.
