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