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