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)
"elements under algorithms" » "elements other algorithms" (Expand Search), "elements de algorithms" (Expand Search), "elements mdem algorithms" (Expand Search), "elements tended algorithms" (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 sampling algorithm") OR ((("elements new algorithm") OR ("elements under algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element sampling algorithm\") OR (((\"elements new algorithm\") OR (\"elements under algorithms\"))))".
• Removing quotes may allow a broader search: (( element sampling algorithm ) OR ((( elements new algorithm ) OR ( elements under algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("element sampling algorithm") OR ((("elements new algorithm") OR ("elements under algorithms"))))*.
