Perhaps you should try some spelling variations:
"element mapping algorithm" » "element sampling algorithm" (Expand Search), "element matching algorithm" (Expand Search), "element mining algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"element means algorithm" » "element search algorithm" (Expand Search), "element mesh algorithm" (Expand Search)
"present data algorithms" » "present art algorithms" (Expand Search), "present all algorithms" (Expand Search), "present de algorithms" (Expand Search), "patient data algorithms" (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 means algorithm\") OR (\"present data algorithms\"))) OR (\"element mapping algorithm\"))~".
• Removing quotes may allow a broader search: (((( element means algorithm ) OR ( present data algorithms ))) OR ( element mapping algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("element means algorithm") OR ("present data algorithms"))) OR ("element mapping algorithm"))*.
