Perhaps you should try some spelling variations:
"binary class whale optimization algorithm" » "binary class swarm optimization algorithm" (Expand Search)
"binary classes based optimization algorithm" » "binary classifiers based optimization algorithm" (Expand Search), "binary cases based optimization algorithm" (Expand Search), "binary clusters based optimization algorithm" (Expand Search), "binary classified 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 class whale optimization algorithm") OR ("binary classes based optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary class whale optimization algorithm\") OR (\"binary classes based optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( binary class whale optimization algorithm ) OR ( binary classes based optimization algorithm ))*.
