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"
"model using methods algorithm" » "model nursing methods algorithm", "model making methods algorithm", "model counting methods algorithm", "code using methods algorithm", "models nursing methods algorithm", "powder using methods algorithm"

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 approximation algorithms") or ("model using methods algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified one approximation algorithms") OR ("model using methods algorithm")).
• Removing quotes may allow a broader search: (( modified one approximation algorithms ) or ( model using methods algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified one approximation algorithms") or ("model using methods algorithm"))*.
