Perhaps you should try some spelling variations:
"data processing algorithm" » "image processing algorithm" (Expand Search)
"element update algorithm" » "element data algorithm" (Expand Search)
"present data algorithm" » "present data algorithms" (Expand Search), "present each algorithm" (Expand Search), "present ddpg algorithm" (Expand Search), "patient data 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: "((((\"element update algorithm\") OR (\"present data algorithm\"))) OR (\"data processing algorithm\"))~".
• Removing quotes may allow a broader search: (((( element update algorithm ) OR ( present data algorithm ))) OR ( data processing algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("element update algorithm") OR ("present data algorithm"))) OR ("data processing algorithm"))*.
