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