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