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)
"post clustering algorithm" » "host clustering algorithm" (Expand Search), "novo clustering algorithm" (Expand Search), "som clustering 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: (((("post clustering algorithm") OR ("cox modeling algorithm"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"post clustering algorithm\") OR (\"cox modeling algorithm\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( post clustering algorithm ) OR ( cox modeling algorithm ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("post clustering algorithm") OR ("cox modeling algorithm"))) OR ("element method algorithm"))*.
