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