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)
"model sorting algorithms" » "model routing algorithm" (Expand Search), "model learning algorithms" (Expand Search), "model working algorithms" (Expand Search), "model forcing algorithms" (Expand Search), "model fitting algorithms" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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 ("model sorting algorithms"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data processing algorithm\") OR (\"model sorting algorithms\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( data processing algorithm ) OR ( model sorting algorithms ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data processing algorithm") OR ("model sorting algorithms"))) OR ("element method algorithm"))*.
