Perhaps you should try some spelling variations:
required optimization » guided optimization (Expand Search), resource optimization (Expand Search), feature optimization (Expand Search)
whale optimization » swarm optimization (Expand Search)
acids required » factors required (Expand Search)
binary acids » binary pairs (Expand Search)
binary mask » binary image (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 acids required optimization algorithm ) OR ( binary mask whale optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( binary acids required optimization algorithm ) OR ( binary mask whale optimization algorithm ))*.
