Perhaps you should try some spelling variations:
"element mapping algorithm" » "element making algorithm" (Expand Search), "element mining algorithm" (Expand Search), "element learning algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "argument mapping algorithm" (Expand Search)
"present model algorithm" » "present novel algorithm" (Expand Search), "present modbo algorithm" (Expand Search), "present modeling algorithm" (Expand Search), "element model algorithm" (Expand Search), "rodent model 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)

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: "((((\"patient data algorithm\") OR (\"present model algorithm\"))) OR (\"element mapping algorithm\"))~".
• Removing quotes may allow a broader search: (((( patient data algorithm ) OR ( present model algorithm ))) OR ( element mapping algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("patient data algorithm") OR ("present model algorithm"))) OR ("element mapping algorithm"))*.
