Perhaps you should try some spelling variations:
"based modeling algorithm" » "based making algorithm" (Expand Search), "based model algorithm" (Expand Search), "based models algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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)

Try widening your search to All Fields.

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

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