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