Perhaps you should try some spelling variations:
"present modeling algorithm" » "present making algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "present model algorithm" (Expand Search), "patient modeling algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"present data algorithm" » "present data algorithms" (Expand Search), "present update algorithm" (Expand Search), "present atlas algorithm" (Expand Search), "presence data algorithm" (Expand Search), "present day algorithm" (Expand Search), "recent data algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("element method algorithm") OR ("present modeling algorithm"))) OR ("present data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithm\") OR (\"present modeling algorithm\"))) OR (\"present data algorithm\"))".
• Removing quotes may allow a broader search: (((( element method algorithm ) OR ( present modeling algorithm ))) OR ( present data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithm") OR ("present modeling algorithm"))) OR ("present data algorithm"))*.
