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