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

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified one approximations algorithm") or ("modified rough approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified one approximations algorithm") OR ("modified rough approximation algorithms")).
• Removing quotes may allow a broader search: (( modified one approximations algorithm ) or ( modified rough approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified one approximations algorithm") or ("modified rough approximation algorithms"))*.
