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)
"derived using algorithms" » "derived pacing algorithms" (Expand Search), "derived nine algorithms" (Expand Search), "derived sorting algorithms" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement 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 ("derived using algorithms"))) OR ("element data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data processing algorithm\") OR (\"derived using algorithms\"))) OR (\"element data algorithm\"))".
• Removing quotes may allow a broader search: (((( data processing algorithm ) OR ( derived using algorithms ))) OR ( element data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data processing algorithm") OR ("derived using algorithms"))) OR ("element data algorithm"))*.
