Perhaps you should try some spelling variations:
"data processing algorithm" » "data modeling algorithm" (Expand Search), "data routing algorithm" (Expand Search), "data tracking algorithm" (Expand Search), "image processing algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element e_ algorithm" » "element _ algorithm" (Expand Search), "element em algorithm" (Expand Search), "element new algorithm" (Expand Search), "element ree algorithm" (Expand Search), "elements _ algorithm" (Expand Search)

Try widening your search to All Fields.

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 e_ algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"element e_ algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( element e_ algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("element e_ algorithm") OR ("element method algorithm"))))*.
