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 forest algorithm" » "element ore algorithm" (Expand Search)
"element rl algorithm" » "element rl algorithms" (Expand Search), "element rf algorithm" (Expand Search), "element ml algorithms" (Expand Search), "element ree algorithm" (Expand Search), "element ore algorithm" (Expand Search), "element _ 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 sampling algorithm"))) OR ("element rl algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element forest algorithm\") OR (\"element sampling algorithm\"))) OR (\"element rl algorithm\"))".
• Removing quotes may allow a broader search: (((( element forest algorithm ) OR ( element sampling algorithm ))) OR ( element rl algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element forest algorithm") OR ("element sampling algorithm"))) OR ("element rl algorithm"))*.
