Perhaps you should try some spelling variations:
"modified passive evolutionary algorithm" » "modified passive evolution algorithm", "modified passive solution algorithm", "modified adaptive evolutionary algorithm"
"modified game optimization algorithm" » "modified game optimization algorithms", "modified game optimisation algorithm", "modified game estimation algorithm", "modified stage optimization algorithm", "modified qoe optimization algorithm", "modified market optimization algorithm", "modified male optimization algorithm", "modified adam optimization 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 passive evolutionary algorithm") OR ("modified game optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified passive evolutionary algorithm\") OR (\"modified game optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( modified passive evolutionary algorithm ) OR ( modified game optimization algorithm ))*.
