Perhaps you should try some spelling variations:
"element matching algorithm" » "element mining algorithm" (Expand Search), "element sampling algorithm" (Expand Search), "element tracking algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "employment matching algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"element group algorithm" » "element growth algorithm" (Expand Search), "elements groups algorithm" (Expand Search), "recent group algorithm" (Expand Search), "supplement group algorithm" (Expand Search)
"elemental _ algorithm" » "elements _ 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: (((("elemental _ algorithm") OR ("element group algorithm"))) OR ("element matching algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elemental _ algorithm\") OR (\"element group algorithm\"))) OR (\"element matching algorithm\"))".
• Removing quotes may allow a broader search: (((( elemental _ algorithm ) OR ( element group algorithm ))) OR ( element matching algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elemental _ algorithm") OR ("element group algorithm"))) OR ("element matching algorithm"))*.
