Perhaps you should try some spelling variations:
"modified graining methods algorithm" » "modified caging methods algorithm", "modified learning methods algorithm", "modified learning method algorithm", "modified making methods 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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified graining methods algorithm") OR ("modified one approximation algorithms"))~.
• Removing quotes may allow a broader search: (( modified graining methods algorithm ) or ( modified one approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified graining methods algorithm") or ("modified one approximation algorithms"))*.
