Perhaps you should try some spelling variations:
"modified elements convolution algorithms" » "modified elements evolution algorithm", "modified elements solution algorithm"
"modified one approximation algorithms" » "modified time approximation algorithms", "modified _ approximation algorithms", "modified rough approximations algorithms", "modified male approximation algorithms", "modified near approximation algorithms", "modified orca approximation 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 elements convolution algorithms\") OR (\"modified one approximation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified elements convolution algorithms ) OR ( modified one approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified elements convolution algorithms") OR ("modified one approximation algorithms"))*.
