Perhaps you should try some spelling variations:
"polynomial-one approximations algorithm" » "polynomial-one approximation algorithm", "polynomial-one approximation algorithms", "polynomial-_ approximation algorithm", "polynomial-time approximation algorithm"
"polynomial-rough approximations algorithm" » "polynomial-rough approximation algorithm", "polynomial-rough approximation algorithms", "polynomial-one approximation 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-one approximations algorithm") OR ("polynomial-rough approximations algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"polynomial-one approximations algorithm\") OR (\"polynomial-rough approximations algorithm\"))".
• Removing quotes may allow a broader search: (( polynomial-one approximations algorithm ) OR ( polynomial-rough approximations algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("polynomial-one approximations algorithm") OR ("polynomial-rough approximations algorithm"))*.
