Perhaps you should try some spelling variations:
"data processing algorithm" » "image processing algorithm" (Expand Search)
"element em algorithm" » "element new algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element _ algorithms" (Expand Search), "element ree algorithm" (Expand Search), "element te algorithm" (Expand Search)
"element rf algorithm" » "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element art algorithms" (Expand Search), "element ree algorithm" (Expand Search), "element ore 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 em algorithm\") OR (\"element rf algorithm\"))))~".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( element em algorithm ) OR ( element rf algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("element em algorithm") OR ("element rf algorithm"))))*.
