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 based case optimization algorithm" » "binary based based optimization algorithm" (Expand Search), "binary based phase optimization algorithm" (Expand Search), "binary based dose optimization algorithm" (Expand Search), "library based case optimization algorithm" (Expand Search), "linac based case optimization algorithm" (Expand Search), "binary mask case optimization algorithm" (Expand Search), "binary base case optimization algorithm" (Expand Search), "binary based cancer 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 process optimization algorithm") OR ("binary based case optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"primary data process optimization algorithm\") OR (\"binary based case optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( primary data process optimization algorithm ) OR ( binary based case optimization algorithm ))*.
