Perhaps you should try some spelling variations:
"element sampling algorithm" » "element modeling algorithm" (Expand Search), "element mining algorithm" (Expand Search), "element matching algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search), "client sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search)
"element making algorithm" » "element learning algorithm" (Expand Search), "element finding algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"client needs algorithm" » "client means algorithm" (Expand Search), "client new algorithm" (Expand Search), "client leiden algorithm" (Expand Search), "urgent needs algorithm" (Expand Search), "china needs 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 sampling algorithm\") OR (\"element making algorithm\"))) OR (\"client needs algorithm\"))~".
• Removing quotes may allow a broader search: (((( element sampling algorithm ) OR ( element making algorithm ))) OR ( client needs algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("element sampling algorithm") OR ("element making algorithm"))) OR ("client needs algorithm"))*.
