Perhaps you should try some spelling variations:
"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"
"powder using methods algorithm" » "powder nursing methods algorithm", "powder making methods algorithm", "powder counting methods algorithm", "code using methods algorithm", "boiler using methods algorithm", "model using methods 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 algorithms") OR ("powder using methods algorithm"))~.
• Removing quotes may allow a broader search: (( modified one approximation algorithms ) or ( powder using methods algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified one approximation algorithms") or ("powder using methods algorithm"))*.
