Perhaps you should try some spelling variations:
"modified a classification algorithm" » "modified _ classification algorithm", "modified gas classification algorithm", "modified image classification algorithm", "modified df classification algorithm", "modified adam classification algorithm"
"modified average approximation algorithms" » "modified _verage approximation algorithms", "modified dfverage approximation algorithms", "modified adamverage approximation algorithms", "modified coverage approximation algorithms"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified average approximation algorithms\") OR (\"modified a classification algorithm\"))~".
• Removing quotes may allow a broader search: (( modified average approximation algorithms ) OR ( modified a classification algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified average approximation algorithms") OR ("modified a classification algorithm"))*.
