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: (((("element method algorithm") OR ("element fusion algorithm"))) OR ("data processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithm\") OR (\"element fusion algorithm\"))) OR (\"data processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element method algorithm ) OR ( element fusion algorithm ))) OR ( data processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithm") OR ("element fusion algorithm"))) OR ("data processing algorithm"))*.
