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)
"client sampling algorithm" » "client making algorithm" (Expand Search), "client modeling algorithm" (Expand Search), "client mining algorithm" (Expand Search)
"element ml algorithms" » "element _ algorithms" (Expand Search), "element g algorithms" (Expand Search), "element te algorithms" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element matching algorithm\") OR (\"client sampling algorithm\"))) OR (\"element ml algorithms\"))~".
• Removing quotes may allow a broader search: (((( element matching algorithm ) OR ( client sampling algorithm ))) OR ( element ml algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("element matching algorithm") OR ("client sampling algorithm"))) OR ("element ml algorithms"))*.
