Perhaps you should try some spelling variations:
based optimization » whale optimization (Expand Search)
phase optimization » whale optimization (Expand Search), path optimization (Expand Search), dose optimization (Expand Search)
pairs based » pairs used (Expand Search)
binary mask » binary image (Expand Search)
mask phase » gas phase (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 pairs based optimization algorithm ) OR ( binary mask phase optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( binary pairs based optimization algorithm ) OR ( binary mask phase optimization algorithm ))*.
