Perhaps you should try some spelling variations:
"data processing algorithm" » "data routing algorithm" (Expand Search), "data tracking algorithm" (Expand Search), "data boosting algorithm" (Expand Search), "image processing algorithm" (Expand Search)
"dft modeling algorithm" » "dft making algorithm" (Expand Search), "data modeling algorithm" (Expand Search), "afm modeling algorithm" (Expand Search), "path modeling algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search), "elements method 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 method algorithm") OR ((("data processing algorithm") OR ("dft modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"data processing algorithm\") OR (\"dft modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( data processing algorithm ) OR ( dft modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("data processing algorithm") OR ("dft modeling algorithm"))))*.
