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