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 pulses optimization algorithms" » "modified pulses optimisation algorithm", "modified pulses estimation algorithms", "modified pulses estimation algorithm", "modified policy 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 delphi convolutional algorithms") OR ("modified pulses optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified delphi convolutional algorithms\") OR (\"modified pulses optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified delphi convolutional algorithms ) OR ( modified pulses optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified delphi convolutional algorithms") OR ("modified pulses optimization algorithms"))*.
