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