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