Perhaps you should try some spelling variations:
"modified deep convolution algorithms" » "modified deep evolution algorithm", "modified deep solution algorithm", "modified deep convolutional algorithms", "modified delphi convolution algorithms", "modified df convolution algorithms", "modified near convolution algorithms"
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one approximation algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified deep convolution algorithms") OR ("modified notion approximation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified deep convolution algorithms\") OR (\"modified notion approximation algorithms\"))*".
• Removing quotes may allow a broader search: (( modified deep convolution algorithms ) OR ( modified notion approximation algorithms ))*.
