Perhaps you should try some spelling variations:
"element sampling algorithm" » "element scheduling algorithm" (Expand Search), "elements sampling algorithm" (Expand Search)
"client sampling algorithm" » "client scheduling algorithm" (Expand Search)
"element rl algorithms" » "element _ algorithms" (Expand Search), "element rd algorithm" (Expand Search), "elements rl algorithms" (Expand Search)

You may be able to get more results by adjusting your search query.

• 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"))))*.
