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