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 update algorithm" » "element pass algorithm" (Expand Search), "element ipca algorithm" (Expand Search), "element monte algorithm" (Expand Search), "element data algorithm" (Expand Search)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both algorithms" (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 update algorithm") OR ("relevant data algorithms"))) OR ("data processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element update algorithm\") OR (\"relevant data algorithms\"))) OR (\"data processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element update algorithm ) OR ( relevant data algorithms ))) OR ( data processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element update algorithm") OR ("relevant data algorithms"))) OR ("data processing algorithm"))*.
