Perhaps you should try some spelling variations:
"modified delphi evolutionary algorithm" » "modified delphi evolution algorithm", "modified delphi solution algorithm"
"modified passive solution algorithms" » "modified passive solution algorithm", "modified passive evolution algorithm", "modified passive convolution algorithms", "modified adaptive solution algorithms", "modified positive solutions algorithms", "modified saline solution 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 evolutionary algorithm") OR ("modified passive solution algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified delphi evolutionary algorithm\") OR (\"modified passive solution algorithms\"))".
• Removing quotes may allow a broader search: (( modified delphi evolutionary algorithm ) OR ( modified passive solution algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified delphi evolutionary algorithm") OR ("modified passive solution algorithms"))*.
