Perhaps you should try some spelling variations:
"client sampling algorithm" » "client making algorithm" (Expand Search), "client modeling algorithm" (Expand Search), "client mining algorithm" (Expand Search)
"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 g algorithms" » "element _ algorithms" (Expand Search), "element 5 algorithms" (Expand Search), "element ml algorithms" (Expand Search), "elements _ algorithms" (Expand Search)

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

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