Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"element rl algorithm" » "element rl algorithms" (Expand Search), "element ml algorithms" (Expand Search), "element _ algorithm" (Expand Search), "element ree algorithm" (Expand Search), "element ore algorithm" (Expand Search)
"element rf algorithm" » "element _ algorithm" (Expand Search), "element em algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element ree algorithm" (Expand Search), "element ore 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 rl algorithm\") OR (\"element rf algorithm\"))))~".
• Removing quotes may allow a broader search: (( client sampling algorithm ) OR ((( element rl algorithm ) OR ( element rf algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("client sampling algorithm") OR ((("element rl algorithm") OR ("element rf algorithm"))))*.
