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)
"element based algorithms" » "element based algorithm" (Expand Search), "engagement based algorithms" (Expand Search)
"element tide algorithm" » "element td3 algorithm" (Expand Search), "element leiden algorithm" (Expand Search), "element five algorithms" (Expand Search), "element te algorithm" (Expand Search), "element model algorithm" (Expand Search), "element study 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 matching algorithm") OR ((("element tide algorithm") OR ("element based algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element matching algorithm\") OR (((\"element tide algorithm\") OR (\"element based algorithms\"))))".
• Removing quotes may allow a broader search: (( element matching algorithm ) OR ((( element tide algorithm ) OR ( element based algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("element matching algorithm") OR ((("element tide algorithm") OR ("element based algorithms"))))*.
