Perhaps you should try some spelling variations:
"case modeling algorithm" » "case making algorithm" (Expand Search), "based modeling algorithm" (Expand Search), "data modeling algorithm" (Expand Search), "a modeling 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 ("case modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"patient data algorithm\") OR (\"element method algorithm\"))) OR (\"case modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( patient data algorithm ) OR ( element method algorithm ))) OR ( case modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("patient data algorithm") OR ("element method algorithm"))) OR ("case modeling algorithm"))*.
