Perhaps you should try some spelling variations:
"elements sampling algorithm" » "elements mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "client sampling 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 means algorithm" » "client search algorithm" (Expand Search), "client 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 means algorithm") OR ("client learner algorithm"))) OR ("elements sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"client means algorithm\") OR (\"client learner algorithm\"))) OR (\"elements sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( client means algorithm ) OR ( client learner algorithm ))) OR ( elements sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("client means algorithm") OR ("client learner algorithm"))) OR ("elements sampling algorithm"))*.
