Perhaps you should try some spelling variations:
based optimization » whale optimization (Expand Search)
codon optimization » wolf optimization (Expand Search)
primary role » primary care (Expand Search), primary goal (Expand Search)
binary basic » binary mask (Expand Search)
basic codon » basic column (Expand Search)
role based » rule based (Expand Search), drone based (Expand Search), home based (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( primary role based optimization algorithm ) OR ( binary basic codon optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( primary role based optimization algorithm ) OR ( binary basic codon optimization algorithm ))*.
