Perhaps you should try some spelling variations:
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one approximation algorithms"
"enabling learning emotion algorithm" » "mapping learning emotion algorithm", "enabling learning evolution algorithm", "enabling learning estimation algorithm", "enabling learning predation algorithm", "enabling learning method algorithm"

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

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