Perhaps you should try some spelling variations:
"modified df convolutional algorithms" » "modified df convolution algorithms", "modified df evolution algorithm", "modified df evolutionary algorithm", "modified d convolutional algorithms", "modified deep convolutional algorithms", "modified _ convolutional algorithms", "modified adam convolutional algorithms"
"modified bi1 approximation algorithms" » "modified time approximation algorithms", "modified _ 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 df convolutional algorithms") OR ("modified bi1 approximation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified df convolutional algorithms\") OR (\"modified bi1 approximation algorithms\"))".
• Removing quotes may allow a broader search: (( modified df convolutional algorithms ) OR ( modified bi1 approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified df convolutional algorithms") OR ("modified bi1 approximation algorithms"))*.
