Perhaps you should try some spelling variations:
process optimization » model optimization (Expand Search)
based optimization » whale optimization (Expand Search)
linac based » lines based (Expand Search)
based based » based case (Expand Search), based basis (Expand Search), ranked based (Expand Search)
hipsc » hips (Expand Search), ipsc (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 hipsc process optimization algorithm ) OR ( linac based based optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( binary hipsc process optimization algorithm ) OR ( linac based based optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( binary hipsc process optimization algorithm ) OR ( linac based based optimization algorithm ))*.
