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)
"element best algorithm" » "element deer algorithm" (Expand Search), "elements best 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: "((\"data processing algorithm\") OR (((\"element best algorithm\") OR (\"element method algorithm\"))))~".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( element best algorithm ) OR ( element method algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("element best algorithm") OR ("element method algorithm"))))*.
