Perhaps you should try some spelling variations:
"primary goal based optimization algorithm" » "primary goal whale optimization algorithm" (Expand Search), "primary tool 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 goal based optimization algorithm") OR ("binary basic codon optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"primary goal based optimization algorithm\") OR (\"binary basic codon optimization algorithm\"))".
• Removing quotes may allow a broader search: (( primary goal based optimization algorithm ) OR ( binary basic codon optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("primary goal based optimization algorithm") OR ("binary basic codon optimization algorithm"))*.
