scale optimization » whale optimization (Expand Search), swarm optimization (Expand Search), phase optimization (Expand Search)
binary marked » binary mask (Expand Search)
marked scale » large scale (Expand Search), care scale (Expand Search)

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