Perhaps you should try some spelling variations:
robust optimization » process optimization (Expand Search), robust estimation (Expand Search), joint optimization (Expand Search)
based optimization » whale optimization (Expand Search)
based robust » based probes (Expand Search)
linac based » lines based (Expand Search)
binary wave » binary image (Expand Search)
wave based » made based (Expand Search), game based (Expand Search), rate based (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 robust optimization algorithms ) OR ( binary wave based optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( linac based robust optimization algorithms ) OR ( binary wave based optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( linac based robust optimization algorithms ) OR ( binary wave based optimization algorithm ))*.
