Perhaps you should try some spelling variations:
"modified graph convolutional algorithms" » "modified graph convolution algorithms", "modified graph evolution algorithm", "modified graph evolutionary algorithm", "modified deep convolutional algorithms", "modified trained convolutional algorithms"
"modified df approximation algorithms" » "modified _ approximation algorithms", "modified one approximation algorithms", "modified time approximation algorithms", "modified adam approximation algorithms", "modified bi1 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 graph convolutional algorithms\") OR (\"modified df approximation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified graph convolutional algorithms ) OR ( modified df approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified graph convolutional algorithms") OR ("modified df approximation algorithms"))*.
