task optimization » based optimization (Expand Search), phase optimization (Expand Search), path optimization (Expand Search)
binary marker » binary mask (Expand Search)
marker whale » marked scale (Expand Search), marker base (Expand Search)
binary back » binary mask (Expand Search)

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( binary marker whale optimization algorithm ) OR ( binary back task optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( binary marker whale optimization algorithm ) OR ( binary back task optimization algorithm ))*.
