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