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 adaptive convolution algorithms" » "modified adaptive evolution algorithm", "modified adaptive solution algorithm", "modified adaptive construction algorithms", "modified adaptive ventilation algorithms", "modified passive convolution 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 adaptive convolution algorithms\") OR (\"modified one approximation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified adaptive convolution algorithms ) OR ( modified one approximation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive convolution algorithms") OR ("modified one approximation algorithm"))*.
