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