Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"element forest algorithm" » "element ore algorithm" (Expand Search)
"element erf algorithm" » "element rf algorithm" (Expand Search), "element em algorithm" (Expand Search), "element rl algorithm" (Expand Search), "element ore algorithm" (Expand Search), "element mesh algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("element forest algorithm") OR ("element erf algorithm"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element forest algorithm\") OR (\"element erf algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( element forest algorithm ) OR ( element erf algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element forest algorithm") OR ("element erf algorithm"))) OR ("client sampling algorithm"))*.
