Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"element mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "element method algorithm" (Expand Search)
"elements ree algorithm" » "elements tree algorithms" (Expand Search), "elements new algorithm" (Expand Search), "elements em algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elements present algorithm" (Expand Search), "elements related 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 ree algorithm") OR ("element mesh algorithm"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements ree algorithm\") OR (\"element mesh algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements ree algorithm ) OR ( element mesh algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements ree algorithm") OR ("element mesh algorithm"))) OR ("client sampling algorithm"))*.
