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)
"client learner algorithm" » "client learning algorithm" (Expand Search), "client learning algorithms" (Expand Search), "client search algorithm" (Expand Search), "client server 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)

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: (((("client needs algorithm") OR ("client learner algorithm"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"client needs algorithm\") OR (\"client learner algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( client needs algorithm ) OR ( client learner algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("client needs algorithm") OR ("client learner algorithm"))) OR ("client sampling algorithm"))*.
