Perhaps you should try some spelling variations:
"polynomial-rough approximationss 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.

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