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)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search)
"element best algorithm" » "element forest algorithm" (Expand Search), "element based algorithm" (Expand Search), "element new algorithm" (Expand Search), "element mesh algorithm" (Expand Search), "element te algorithm" (Expand Search), "element fbe 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 best algorithm"))) OR ("data using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithm\") OR (\"element best algorithm\"))) OR (\"data using algorithm\"))".
• Removing quotes may allow a broader search: (((( element method algorithm ) OR ( element best algorithm ))) OR ( data using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithm") OR ("element best algorithm"))) OR ("data using algorithm"))*.
