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