Perhaps you should try some spelling variations:
"data processing algorithm" » "data processing algorithms" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"relevant data algorithm" » "relevant jaya algorithm" (Expand Search), "relevant deer 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 processing algorithm") OR ((("element method algorithm") OR ("relevant data algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"element method algorithm\") OR (\"relevant data algorithm\"))))*".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( element method algorithm ) OR ( relevant data algorithm ))))*.
