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 parameter optimization algorithms" » "modified parameter optimisation algorithm", "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameters optimization algorithms"

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

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