Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling 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)
"element rf algorithm" » "element _ algorithm" (Expand Search), "element em algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element ore algorithm" (Expand Search), "element te 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 rf algorithm") OR ("element ree algorithm"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element rf algorithm\") OR (\"element ree algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( element rf algorithm ) OR ( element ree algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element rf algorithm") OR ("element ree algorithm"))) OR ("client sampling algorithm"))*.
