Perhaps you should try some spelling variations:
"binary risk based optimization algorithm" » "binary risk whale optimization algorithm" (Expand Search), "primary risk based optimization algorithm" (Expand Search), "dietary risk based optimization algorithm" (Expand Search)
"binary basic _ optimization algorithm" » "binary mask _ 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 risk based optimization algorithm\") OR (\"binary basic _ optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( binary risk based optimization algorithm ) OR ( binary basic _ optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("binary risk based optimization algorithm") OR ("binary basic _ optimization algorithm"))*.
