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