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