Perhaps you should try some spelling variations:
"binary risk bayesian optimization algorithm" » "binary risk based optimization algorithm" (Expand Search)
"binary image task optimization algorithm" » "binary image based optimization algorithm" (Expand Search), "binary image hawks optimization algorithm" (Expand Search), "binary image 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 risk bayesian optimization algorithm") OR ("binary image task optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary risk bayesian optimization algorithm\") OR (\"binary image task optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( binary risk bayesian optimization algorithm ) OR ( binary image task optimization algorithm ))*.
