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