Perhaps you should try some spelling variations:
"element sampling algorithm" » "sediment sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "client sampling algorithm" (Expand Search)
"client mining algorithm" » "client learning algorithm" (Expand Search), "client means algorithm" (Expand Search)
"client search algorithm" » "line search algorithm" (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 sampling algorithm\") OR (((\"client mining algorithm\") OR (\"client search algorithm\"))))~".
• Removing quotes may allow a broader search: (( element sampling algorithm ) OR ((( client mining algorithm ) OR ( client search algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("element sampling algorithm") OR ((("client mining algorithm") OR ("client search algorithm"))))*.
