Perhaps you should try some spelling variations:
"client sampling algorithm" » "client scheduling algorithm" (Expand Search)
"element rf algorithm" » "element rd algorithm" (Expand Search), "element _ algorithms" (Expand Search), "elements rf algorithm" (Expand Search)
"element matching algorithm" » "elements matching algorithm" (Expand Search), "element machine algorithm" (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 matching algorithm\") OR (\"client sampling algorithm\"))) OR (\"element rf algorithm\"))~".
• Removing quotes may allow a broader search: (((( element matching algorithm ) OR ( client sampling algorithm ))) OR ( element rf algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("element matching algorithm") OR ("client sampling algorithm"))) OR ("element rf algorithm"))*.
