Perhaps you should try some spelling variations:
"modified rough approximations algorithms" » "modified rough approximation algorithms", "modified rough approximation algorithm", "modified one approximation algorithms"
"enabling learning method algorithm" » "mapping learning method algorithm", "enabling learning mom algorithm", "enabling learning methods algorithm", "enabling graining methods algorithm", "enabling learning emotion 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: (("enabling learning method algorithm") OR ("modified rough approximations algorithms"))~.
• Removing quotes may allow a broader search: (( enabling learning method algorithm ) or ( modified rough approximations algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("enabling learning method algorithm") or ("modified rough approximations algorithms"))*.
