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