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