Perhaps you should try some spelling variations:
"binary rat guided optimization algorithm" » "binary rat spider optimization algorithm" (Expand Search), "binary rat based optimization algorithm" (Expand Search), "binary rat inspired optimization algorithm" (Expand Search), "binary graph guided optimization algorithm" (Expand Search)
"binary rank level optimization algorithm" » "binary rank global optimization algorithm" (Expand Search), "binary rank based optimization algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("binary rat guided optimization algorithm") OR ("binary rank level optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary rat guided optimization algorithm\") OR (\"binary rank level optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( binary rat guided optimization algorithm ) OR ( binary rank level optimization algorithm ))*.
