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), "client sampling algorithm" (Expand Search)
"elements over algorithm" » "elements novel algorithm" (Expand Search), "elements other algorithms" (Expand Search), "elements new algorithm" (Expand Search), "elements under algorithm" (Expand Search), "events over algorithm" (Expand Search), "elements ree 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 ("elements over algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element rl algorithms\") OR (((\"element sampling algorithm\") OR (\"elements over algorithm\"))))".
• Removing quotes may allow a broader search: (( element rl algorithms ) OR ((( element sampling algorithm ) OR ( elements over algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element rl algorithms") OR ((("element sampling algorithm") OR ("elements over algorithm"))))*.
