Perhaps you should try some spelling variations:
"modified coverage approximation algorithms" » "modified average approximation algorithms"
"modified one approximation algorithm" » "modified time approximation algorithm", "modified _ approximation algorithm", "modified rough approximations algorithm", "modified male approximation algorithm", "modified near approximation algorithm", "modified orca approximation algorithm"

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