Perhaps you should try some spelling variations:
"data sample process optimization algorithm" » "data sample model optimization algorithm" (Expand Search), "data simple process optimization algorithm" (Expand Search), "data same process optimization algorithm" (Expand Search), "data sample processing optimization algorithm" (Expand Search), "data samples process optimization algorithm" (Expand Search)
"binary data _ optimization algorithm" » "primary data _ optimization algorithm" (Expand Search), "dietary data _ 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 process optimization algorithm") OR ("binary data _ optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data sample process optimization algorithm\") OR (\"binary data _ optimization algorithm\"))".
• Removing quotes may allow a broader search: (( data sample process optimization algorithm ) OR ( binary data _ optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("data sample process optimization algorithm") OR ("binary data _ optimization algorithm"))*.
