Perhaps you should try some spelling variations:
"Polynomial-rough approximation algorithm" » "Polynomial-rough approximation algorithms", "Polynomial-rough approximations algorithm"
"Polynomial-one approximation algorithm" » "Polynomial-one approximation algorithms", "Polynomial-time approximation algorithm", "Polynomial-_ approximation algorithm", "Polynomial-rough approximations algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("Polynomial-rough approximation algorithm") OR ("Polynomial-one approximation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"Polynomial-rough approximation algorithm\") OR (\"Polynomial-one approximation algorithm\"))".
• Removing quotes may allow a broader search: (( Polynomial-rough approximation algorithm ) OR ( Polynomial-one approximation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("Polynomial-rough approximation algorithm") OR ("Polynomial-one approximation algorithm"))*.
