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 data robust optimization algorithm" » "binary rat robust 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 data robust optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"primary data driven optimization algorithm\") OR (\"binary data robust optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( primary data driven optimization algorithm ) OR ( binary data robust optimization algorithm ))*.
