Perhaps you should try some spelling variations:
"element matching algorithm" » "element making algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "element mining algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "employment matching algorithm" (Expand Search)
"elements based algorithm" » "experiments based algorithm" (Expand Search), "elements related algorithm" (Expand Search)
"element ore algorithm" » "element rf algorithm" (Expand Search), "element rl algorithm" (Expand Search), "element erf algorithm" (Expand Search), "element te algorithm" (Expand Search), "element fbe algorithm" (Expand Search), "element ree 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: (((("elements based algorithm") OR ("element ore algorithm"))) OR ("element matching algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements based algorithm\") OR (\"element ore algorithm\"))) OR (\"element matching algorithm\"))".
• Removing quotes may allow a broader search: (((( elements based algorithm ) OR ( element ore algorithm ))) OR ( element matching algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements based algorithm") OR ("element ore algorithm"))) OR ("element matching algorithm"))*.
