Perhaps you should try some spelling variations:
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one approximation algorithms"
"modified learning emotion algorithm" » "mobile learning emotion algorithm", "modified caging emotion algorithm", "modified learning evolution algorithm", "modified learning estimation algorithm", "modified learning predation algorithm", "modified 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: (("modified learning emotion algorithm") OR ("modified notion approximation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified learning emotion algorithm\") OR (\"modified notion approximation algorithms\"))".
• Removing quotes may allow a broader search: (( modified learning emotion algorithm ) OR ( modified notion approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified learning emotion algorithm") OR ("modified notion approximation algorithms"))*.
