Perhaps you should try some spelling variations:
"primary data codes optimization algorithm" » "primary data spider optimization algorithm" (Expand Search), "primary data based optimization algorithm" (Expand Search), "primary data igdt optimization algorithm" (Expand Search), "primary data models optimization algorithm" (Expand Search)
"binary basic global optimization algorithm" » "binary basis global 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 codes optimization algorithm") OR ("binary basic global optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"primary data codes optimization algorithm\") OR (\"binary basic global optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( primary data codes optimization algorithm ) OR ( binary basic global optimization algorithm ))*.
