Perhaps you should try some spelling variations:
"binary maps whale optimization algorithm" » "binary maps swarm optimization algorithm" (Expand Search), "binary mass whale optimization algorithm" (Expand Search), "binary gaps whale optimization algorithm" (Expand Search), "binary map whale optimization algorithm" (Expand Search)
"binary images based optimization algorithm" » "binary states 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 maps whale optimization algorithm") OR ("binary images based optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"binary maps whale optimization algorithm\") OR (\"binary images based optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( binary maps whale optimization algorithm ) OR ( binary images based optimization algorithm ))*.
