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 quadratic optimization algorithms" » "modified quadratic optimisation algorithm", "modified quadratic estimation algorithms", "modified quadratic estimation algorithm", "modified static optimization algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified quadratic optimization algorithms") or ("modified delphi convolutional algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified quadratic optimization algorithms") OR ("modified delphi convolutional algorithms"))*.
• Removing quotes may allow a broader search: (( modified quadratic optimization algorithms ) or ( modified delphi convolutional algorithms ))*.
