Perhaps you should try some spelling variations:
"binary ratssesse based optimization algorithm" » "binary ratessesse based optimization algorithm" (Expand Search), "binary ratsssesse based optimization algorithm" (Expand Search)
"binary rat swarm optimization algorithm" » "binary rate swarm optimization algorithm" (Expand Search), "binary rats swarm optimization algorithm" (Expand Search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary ratssesse based optimization algorithm\") OR (\"binary rat swarm optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( binary ratssesse based optimization algorithm ) OR ( binary rat swarm optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("binary ratssesse based optimization algorithm") OR ("binary rat swarm optimization algorithm"))*.
