Perhaps you should try some spelling variations:
"binary rat global optimization algorithm" » "binary rate global optimization algorithm" (Expand Search), "binary rats global optimization algorithm" (Expand Search)
"binary simple swarm optimization algorithm" » "binary sample swarm 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 global optimization algorithm") OR ("binary simple swarm optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary rat global optimization algorithm\") OR (\"binary simple swarm optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( binary rat global optimization algorithm ) OR ( binary simple swarm optimization algorithm ))*.
