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)
"end processing algorithm" » "end modeling algorithm" (Expand Search), "end routing algorithm" (Expand Search), "end tracking algorithm" (Expand Search), "rna processing algorithm" (Expand Search), "wood processing algorithm" (Expand Search), "food processing algorithm" (Expand Search)
"element update algorithm" » "element pass algorithm" (Expand Search), "element data algorithms" (Expand Search), "element ipca algorithm" (Expand Search), "element data 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 ("end processing algorithm"))) OR ("element update algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data processing algorithm\") OR (\"end processing algorithm\"))) OR (\"element update algorithm\"))".
• Removing quotes may allow a broader search: (((( data processing algorithm ) OR ( end processing algorithm ))) OR ( element update algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data processing algorithm") OR ("end processing algorithm"))) OR ("element update algorithm"))*.
