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