Perhaps you should try some spelling variations:
features optimization » feature optimization (Expand Search), mixture optimization (Expand Search), resource optimization (Expand Search)
based optimization » whale optimization (Expand Search)
level features » local features (Expand Search)
binary level » urinary levels (Expand Search), primary level (Expand Search), entry level (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 level features optimization algorithm ) OR ( binary task based optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( binary level features optimization algorithm ) OR ( binary task based optimization algorithm ))*.
