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