Perhaps you should try some spelling variations:
process optimization » model optimization (Expand Search)
linear optimization » lead optimization (Expand Search), after optimization (Expand Search)
based linear » based library (Expand Search), best linear (Expand Search), wise linear (Expand Search)
linac based » lines based (Expand Search)
mod process » word process (Expand Search), amos process (Expand Search), from process (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 linear optimization algorithm ) OR ( binary mod process optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( linac based linear optimization algorithm ) OR ( binary mod process optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( linac based linear optimization algorithm ) OR ( binary mod process optimization algorithm ))*.
