binary basic » binary mask (Expand Search)
basic target » based target (Expand Search), main target (Expand Search), six target (Expand Search)
linac based » lines based (Expand Search)
based swarm » based sars (Expand Search), based smart (Expand Search), based arm (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: (( linac based swarm optimization algorithm ) OR ( binary basic target detection algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( linac based swarm optimization algorithm ) OR ( binary basic target detection algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( linac based swarm optimization algorithm ) OR ( binary basic target detection algorithm ))*.
