Perhaps you should try some spelling variations:
"data processing algorithm" » "data processing algorithms" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"element fusion algorithm" » "element auction algorithm" (Expand Search), "element cosine algorithm" (Expand Search), "elements fusion 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: (("data processing algorithm") OR ((("element method algorithm") OR ("element fusion algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"element method algorithm\") OR (\"element fusion algorithm\"))))".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( element method algorithm ) OR ( element fusion algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("element method algorithm") OR ("element fusion algorithm"))))*.
