Perhaps you should try some spelling variations:
required optimization » guided optimization (Expand Search), resource optimization (Expand Search), feature optimization (Expand Search)
based optimization » whale optimization (Expand Search)
space required » force required (Expand Search), size required (Expand Search)
binary space » binary image (Expand Search), banach space (Expand Search)
binary task » binary mask (Expand Search)
task based » risk based (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 space required optimization algorithm ) OR ( binary task based optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( binary space required optimization algorithm ) OR ( binary task based optimization algorithm ))*.
