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