Perhaps you should try some spelling variations:
"modified trained convolutional algorithms" » "modified trained convolution algorithms", "modified trained evolution algorithm", "modified trained evolutionary algorithm", "modified graph convolutional algorithms", "modified traces convolutional algorithms"
"modified coverage approximation algorithms" » "modified average 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 coverage approximation algorithms") OR ("modified trained convolutional algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified coverage approximation algorithms\") OR (\"modified trained convolutional algorithms\"))*".
• Removing quotes may allow a broader search: (( modified coverage approximation algorithms ) OR ( modified trained convolutional algorithms ))*.
