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