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.

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