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