Perhaps you should try some spelling variations:
"modified one approximation algorithm" » "modified one approximation algorithms", "modified time approximation algorithm", "modified _ approximation algorithm", "modified rough approximations algorithm", "modified male approximation algorithm", "modified near approximation algorithm", "modified orca approximation algorithm"
"modified response estimation algorithms" » "modified response estimation algorithm", "modified response optimization algorithms", "modified response optimisation algorithm", "modified pose estimation algorithms", "modified response association algorithms"

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: "((\"modified one approximation algorithm\") OR (\"modified response estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified one approximation algorithm ) OR ( modified response estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified one approximation algorithm") OR ("modified response estimation algorithms"))*.
