Perhaps you should try some spelling variations:
"modified time approximation algorithm" » "modified time approximation algorithms", "modified one approximation algorithm", "modified _ approximation algorithm", "modified bi1 approximation algorithm", "modified male approximation algorithm"
"modified deep convolutional algorithm" » "modified deep convolution algorithms", "modified deep evolution algorithm", "modified deep evolutionary algorithm", "modified d convolutional algorithm", "modified graph convolutional algorithm", "modified delphi convolutional algorithm", "modified df convolutional algorithm", "modified near convolutional algorithm"

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 convolutional algorithm") OR ("modified time approximation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified deep convolutional algorithm\") OR (\"modified time approximation algorithm\"))".
• Removing quotes may allow a broader search: (( modified deep convolutional algorithm ) OR ( modified time approximation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified deep convolutional algorithm") OR ("modified time approximation algorithm"))*.
