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