Perhaps you should try some spelling variations:
"data processing algorithm" » "data processing algorithms" (Expand Search)
"element update algorithm" » "elements update algorithm" (Expand Search), "element updated algorithm" (Expand Search)
"element citre algorithms" » "elements citre algorithms" (Expand Search), "element cite algorithms" (Expand Search), "element titre 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 ("element citre algorithms"))) OR ("data processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element update algorithm\") OR (\"element citre algorithms\"))) OR (\"data processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element update algorithm ) OR ( element citre algorithms ))) OR ( data processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element update algorithm") OR ("element citre algorithms"))) OR ("data processing algorithm"))*.
