Perhaps you should try some spelling variations:
"modified invasive convolution algorithms" » "modified invasive evolution algorithm", "modified invasive solution algorithm", "modified invasive ventilation algorithms", "modified passive convolution algorithms"
"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 one approximation algorithms\") OR (\"modified invasive convolution algorithms\"))~".
• Removing quotes may allow a broader search: (( modified one approximation algorithms ) OR ( modified invasive convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified one approximation algorithms") OR ("modified invasive convolution algorithms"))*.
