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 means algorithm" » "element search algorithm" (Expand Search), "element mesh algorithm" (Expand Search)
"element forest algorithm" » "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 means algorithm\"))) OR (\"element forest algorithm\"))~".
• Removing quotes may allow a broader search: (((( client sampling algorithm ) OR ( element means algorithm ))) OR ( element forest algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("client sampling algorithm") OR ("element means algorithm"))) OR ("element forest algorithm"))*.
