Perhaps you should try some spelling variations:
"primary data driven optimization algorithm" » "primary data level optimization algorithm" (Expand Search), "primary data spider optimization algorithm" (Expand Search)
"binary step wolf optimization algorithm" » "binary step whale optimization algorithm" (Expand Search), "binary step policy optimization algorithm" (Expand Search), "binary step swarm 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 driven optimization algorithm") OR ("binary step wolf optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"primary data driven optimization algorithm\") OR (\"binary step wolf optimization algorithm\"))".
• Removing quotes may allow a broader search: (( primary data driven optimization algorithm ) OR ( binary step wolf optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("primary data driven optimization algorithm") OR ("binary step wolf optimization algorithm"))*.
