Perhaps you should try some spelling variations:
"data processing algorithm" » "data modeling algorithm" (Expand Search), "data routing algorithm" (Expand Search), "data tracking algorithm" (Expand Search), "image processing algorithm" (Expand Search)
"element based algorithms" » "element based algorithm" (Expand Search), "engagement based algorithms" (Expand Search)
"element mean algorithm" » "element means algorithm" (Expand Search), "element new algorithm" (Expand Search), "element each algorithm" (Expand Search), "element mesh algorithm" (Expand Search), "latent mean algorithm" (Expand Search), "element te 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: (("data processing algorithm") OR ((("element based algorithms") OR ("element mean algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"element based algorithms\") OR (\"element mean algorithm\"))))".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( element based algorithms ) OR ( element mean algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("element based algorithms") OR ("element mean algorithm"))))*.
