Perhaps you should try some spelling variations:
"modified delphi convolutional algorithms" » "modified delphi evolution algorithm", "modified delphi evolutionary algorithm", "modified deep convolutional algorithms", "modified graph convolutional algorithms", "modified d convolutional algorithms"
"modified invasive convolution algorithms" » "modified invasive evolution algorithm", "modified invasive solution algorithm", "modified invasive ventilation algorithms", "modified passive convolution algorithms"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified delphi convolutional algorithms") OR ("modified invasive convolution algorithms"))~.
• Removing quotes may allow a broader search: (( modified delphi convolutional algorithms ) or ( modified invasive convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified delphi convolutional algorithms") or ("modified invasive convolution algorithms"))*.
