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