Perhaps you should try some spelling variations:
"primary data process optimization algorithm" » "primary data model optimization algorithm" (Expand Search), "primary care process optimization algorithm" (Expand Search), "primary data processing optimization algorithm" (Expand Search), "primary damage process optimization algorithm" (Expand Search), "primary data access optimization algorithm" (Expand Search)
"binary data robust optimization algorithm" » "binary data robust estimation algorithm" (Expand Search), "binary data joint optimization algorithm" (Expand Search), "dietary data robust optimization algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"primary data process optimization algorithm\") OR (\"binary data robust optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( primary data process optimization algorithm ) OR ( binary data robust optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("primary data process optimization algorithm") OR ("binary data robust optimization algorithm"))*.
