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 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)
"element rf algorithm" » "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element art algorithms" (Expand Search), "element ore algorithm" (Expand Search), "element ree 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 rf algorithm") OR ("element mean algorithm"))) OR ("data processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element rf algorithm\") OR (\"element mean algorithm\"))) OR (\"data processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element rf algorithm ) OR ( element mean algorithm ))) OR ( data processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element rf algorithm") OR ("element mean algorithm"))) OR ("data processing algorithm"))*.
