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