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