Perhaps you should try some spelling variations:
"primary risk codon optimization algorithm" » "primary risk wolf optimization algorithm" (Expand Search), "primary aim codon optimization algorithm" (Expand Search), "primary role codon optimization algorithm" (Expand Search)
"binary basic based optimization algorithm" » "binary basic whale optimization algorithm" (Expand Search), "binary mask based optimization algorithm" (Expand Search), "binary music based optimization algorithm" (Expand Search), "binary basic gases optimization algorithm" (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: (("primary risk codon optimization algorithm") OR ("binary basic based optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"primary risk codon optimization algorithm\") OR (\"binary basic based optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( primary risk codon optimization algorithm ) OR ( binary basic based optimization algorithm ))*.
