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)
"element rl algorithm" » "element rl algorithms" (Expand Search), "element rf algorithm" (Expand Search), "element ml algorithms" (Expand Search), "element ree algorithm" (Expand Search), "element ore algorithm" (Expand Search), "element _ 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 rl algorithm") OR ("element mesh algorithm"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element rl algorithm\") OR (\"element mesh algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( element rl algorithm ) OR ( element mesh algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element rl algorithm") OR ("element mesh algorithm"))) OR ("client sampling algorithm"))*.
