Perhaps you should try some spelling variations:
"element sampling algorithm" » "element making algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "element mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search), "client sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search)
"elements other algorithms" » "elements three algorithms" (Expand Search), "elements tree algorithms" (Expand Search), "elements both algorithms" (Expand Search), "elements over algorithms" (Expand Search), "elements under algorithms" (Expand Search)
"element rf algorithm" » "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element art algorithms" (Expand Search), "element ore algorithm" (Expand Search), "element ree 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: (("elements other algorithms") OR ((("element sampling algorithm") OR ("element rf algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements other algorithms\") OR (((\"element sampling algorithm\") OR (\"element rf algorithm\"))))".
• Removing quotes may allow a broader search: (( elements other algorithms ) OR ((( element sampling algorithm ) OR ( element rf algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements other algorithms") OR ((("element sampling algorithm") OR ("element rf algorithm"))))*.
