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