Perhaps you should try some spelling variations:
whale optimization » swarm optimization (Expand Search)
case optimization » based optimization (Expand Search), phase optimization (Expand Search), dose optimization (Expand Search)
marker whale » marked scale (Expand Search), marker base (Expand Search)
binary mask » binary image (Expand Search)
mask case » mask based (Expand Search), base case (Expand Search), case case (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 marker whale optimization algorithm ) OR ( binary mask case optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( binary marker whale optimization algorithm ) OR ( binary mask case optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( binary marker whale optimization algorithm ) OR ( binary mask case optimization algorithm ))*.
