Perhaps you should try some spelling variations:
"data sample processing optimization algorithm" » "data image processing optimization algorithm" (Expand Search), "data melt processing optimization algorithm" (Expand Search)
"binary data _ optimization algorithm" » "binary rat _ 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: (("data sample processing optimization algorithm") OR ("binary data _ optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data sample processing optimization algorithm\") OR (\"binary data _ optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( data sample processing optimization algorithm ) OR ( binary data _ optimization algorithm ))*.
