Perhaps you should try some spelling variations:
"elements sampling algorithm" » "elements mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "client sampling algorithm" (Expand Search)
"element ree algorithm" » "element tree algorithms" (Expand Search), "element em algorithm" (Expand Search), "element rf algorithm" (Expand Search), "elements ree algorithm" (Expand Search), "element te algorithm" (Expand Search), "element mesh algorithm" (Expand Search)
"elements new algorithm" » "elements novel algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elements ree algorithm" (Expand Search), "elements fe algorithm" (Expand Search), "elements res algorithm" (Expand Search)

Try widening your search to All Fields.

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

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