Perhaps you should try some spelling variations:
required optimization » guided optimization (Expand Search), resource optimization (Expand Search), feature optimization (Expand Search)
codon optimization » wolf optimization (Expand Search)
risks required » costs required (Expand Search)
binary risks » dietary risks (Expand Search), binary mask (Expand Search)
binary b » binary _ (Expand Search)
b codon » _ codon (Expand Search), b common (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 risks required optimization algorithm ) OR ( binary b codon optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( binary risks required optimization algorithm ) OR ( binary b codon optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( binary risks required optimization algorithm ) OR ( binary b codon optimization algorithm ))*.
