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 location estimation algorithms" » "modified location estimation algorithm", "modified location optimization algorithms", "modified location optimisation algorithm", "modified motion estimation algorithms", "modified carbon estimation algorithms"

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