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