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 rough approximation algorithms\") OR (\"modified based convolution algorithms\"))~".
• Removing quotes may allow a broader search: (( modified rough approximation algorithms ) OR ( modified based convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified rough approximation algorithms") OR ("modified based convolution algorithms"))*.
