Perhaps you should try some spelling variations:
"modified delphi convolutional algorithms" » "modified delphi convolution algorithms", "modified delphi evolution algorithm", "modified deep convolutional algorithms", "modified graph convolutional algorithms", "modified d convolutional algorithms"
"modified positive evolutionary algorithm" » "modified positive evolution algorithm", "modified positive solution algorithm", "modified objective evolutionary algorithm", "modified positive solutions algorithm", "modified passive evolutionary algorithm", "modified adaptive evolutionary algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified positive evolutionary algorithm") OR ("modified delphi convolutional algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified positive evolutionary algorithm\") OR (\"modified delphi convolutional algorithms\"))".
• Removing quotes may allow a broader search: (( modified positive evolutionary algorithm ) OR ( modified delphi convolutional algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified positive evolutionary algorithm") OR ("modified delphi convolutional algorithms"))*.
