Perhaps you should try some spelling variations:
"client sampling algorithm" » "client making algorithm" (Expand Search), "client modeling algorithm" (Expand Search), "client mining algorithm" (Expand Search)
"elements tree algorithms" » "elements three algorithms" (Expand Search), "elements art algorithms" (Expand Search), "elements two algorithms" (Expand Search), "elements ree algorithms" (Expand Search), "element ree algorithms" (Expand Search), "elements res algorithms" (Expand Search)
"element ore algorithm" » "element rf algorithm" (Expand Search), "element rl algorithm" (Expand Search), "element erf algorithm" (Expand Search), "element te algorithm" (Expand Search), "element fbe algorithm" (Expand Search), "element ree algorithm" (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 ore algorithm") OR ((("client sampling algorithm") OR ("elements tree algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element ore algorithm\") OR (((\"client sampling algorithm\") OR (\"elements tree algorithms\"))))".
• Removing quotes may allow a broader search: (( element ore algorithm ) OR ((( client sampling algorithm ) OR ( elements tree algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("element ore algorithm") OR ((("client sampling algorithm") OR ("elements tree algorithms"))))*.
