Perhaps you should try some spelling variations:
scale optimization » whale optimization (Expand Search), swarm optimization (Expand Search), phase optimization (Expand Search)
based optimization » whale optimization (Expand Search)
binary marked » binary mask (Expand Search)
marked scale » large scale (Expand Search), care scale (Expand Search)
binary gas » binary mask (Expand Search), binary pairs (Expand Search)
gas based » ms based (Expand Search), grades based (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( binary marked scale optimization algorithm ) OR ( binary gas based optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( binary marked scale optimization algorithm ) OR ( binary gas based optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( binary marked scale optimization algorithm ) OR ( binary gas based optimization algorithm ))*.
