Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"modified delphi convolutional algorithm" » "modified delphi convolution algorithms", "modified delphi evolution algorithm", "modified delphi evolutionary algorithm", "modified deep convolutional algorithm", "modified graph convolutional algorithm", "modified d convolutional 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 multiobjective optimizer algorithms") OR ("modified delphi convolutional algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimizer algorithms\") OR (\"modified delphi convolutional algorithm\"))".
• Removing quotes may allow a broader search: (( modified multiobjective optimizer algorithms ) OR ( modified delphi convolutional algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimizer algorithms") OR ("modified delphi convolutional algorithm"))*.
