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 passive ventilation algorithms" » "modified passive estimation algorithms", "modified passive estimation algorithm", "modified passive convolution algorithms", "modified adaptive ventilation algorithms", "modified invasive ventilation 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 delphi convolutional algorithms\") OR (\"modified passive ventilation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified delphi convolutional algorithms ) OR ( modified passive ventilation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified delphi convolutional algorithms") OR ("modified passive ventilation algorithms"))*.
