Perhaps you should try some spelling variations:
"modified coverage approximation algorithm" » "modified average approximation algorithm"
"modified adam approximation algorithms" » "modified _ approximation algorithms", "modified one approximation algorithms", "modified time approximation algorithms", "modified df approximation algorithms", "modified near approximation algorithms"

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: (("modified coverage approximation algorithm") OR ("modified adam approximation algorithms"))~.
• Removing quotes may allow a broader search: (( modified coverage approximation algorithm ) or ( modified adam approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified coverage approximation algorithm") or ("modified adam approximation algorithms"))*.
