Perhaps you should try some spelling variations:
based optimization » whale optimization (Expand Search)
a optimization » ai optimization (Expand Search), _ optimization (Expand Search), b optimization (Expand Search)
binary mask » binary image (Expand Search)
binary vr » binary _ (Expand Search), binary b (Expand Search)
vr based » pcr based (Expand Search), mer based (Expand Search), _ based (Expand Search)
mask a » mask _ (Expand Search), task a (Expand Search), ask a (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 vr based optimization algorithm ) OR ( binary mask a optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( binary vr based optimization algorithm ) OR ( binary mask a optimization algorithm ))*.
