Perhaps you should try some spelling variations:
"modified delphi convolutional algorithms" » "modified delphi convolution algorithms", "modified delphi evolutionary algorithm", "modified deep convolutional algorithms", "modified graph convolutional algorithms", "modified d convolutional algorithms"
"modified positive evolution algorithm" » "modified positive solution algorithm", "modified positive evolutionary algorithm", "modified positive convolution algorithms", "modified positive solutions algorithm", "modified passive evolution algorithm", "modified adaptive evolution 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 delphi convolutional algorithms") or ("modified positive evolution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified delphi convolutional algorithms") OR ("modified positive evolution algorithm")).
• Removing quotes may allow a broader search: (( modified delphi convolutional algorithms ) or ( modified positive evolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified delphi convolutional algorithms") or ("modified positive evolution algorithm"))*.
