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)
"trained using algorithm" » "trained using algorithms" (Expand Search), "trained routing algorithm" (Expand Search), "trained fusion algorithm" (Expand Search), "obtained using algorithm" (Expand Search), "examined using algorithm" (Expand Search), "determined using 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 ("trained using algorithm"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data processing algorithm\") OR (\"trained using algorithm\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( data processing algorithm ) OR ( trained using algorithm ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data processing algorithm") OR ("trained using algorithm"))) OR ("element method algorithm"))*.
