Perhaps you should try some spelling variations:
"element custom algorithm" » "element fusion algorithm" (Expand Search), "element control algorithm" (Expand Search), "element lasso algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"data based algorithm" » "data used 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 custom algorithm") OR ("element method algorithm"))) OR ("data based algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element custom algorithm\") OR (\"element method algorithm\"))) OR (\"data based algorithm\"))".
• Removing quotes may allow a broader search: (((( element custom algorithm ) OR ( element method algorithm ))) OR ( data based algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element custom algorithm") OR ("element method algorithm"))) OR ("data based algorithm"))*.
