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 solution algorithm" » "modified passive evolution algorithm", "modified passive convolution algorithms", "modified passive evolutionary algorithm", "modified adaptive solution algorithm", "modified positive solutions algorithm", "modified saline solution algorithm"

Try widening your search to All Fields.

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