Perhaps you should try some spelling variations:
whale optimization » swarm optimization (Expand Search)
wolf optimization » swarm optimization (Expand Search), _ optimization (Expand Search)
binary case » binary mask (Expand Search), binary image (Expand Search), primary case (Expand Search)
binary a » binary _ (Expand Search), binary b (Expand Search), hilary a (Expand Search)
a wolf » _ wolf (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 case whale optimization algorithm ) OR ( binary a wolf optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( binary case whale optimization algorithm ) OR ( binary a wolf optimization algorithm ))*.
