Perhaps you should try some spelling variations:
robust optimization » process optimization (Expand Search), robust estimation (Expand Search), joint optimization (Expand Search)
whale optimization » swarm optimization (Expand Search)
binary immune » primary immune (Expand Search)
immune robust » immune cost (Expand Search)
image whale » image scale (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 immune robust optimization algorithm ) OR ( binary image whale optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( binary immune robust optimization algorithm ) OR ( binary image whale optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( binary immune robust optimization algorithm ) OR ( binary image whale optimization algorithm ))*.
