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" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"elements em algorithm" » "elements new algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elements _ algorithms" (Expand Search), "elements ree algorithm" (Expand Search), "elements ppm 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: (("elements em algorithm") OR ((("elements sampling algorithm") OR ("client sampling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements em algorithm\") OR (((\"elements sampling algorithm\") OR (\"client sampling algorithm\"))))".
• Removing quotes may allow a broader search: (( elements em algorithm ) OR ((( elements sampling algorithm ) OR ( client sampling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements em algorithm") OR ((("elements sampling algorithm") OR ("client sampling algorithm"))))*.
