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