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