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 needs algorithm" » "client means algorithm" (Expand Search), "client new algorithm" (Expand Search), "client leiden algorithm" (Expand Search), "china needs algorithm" (Expand Search), "urgent needs algorithm" (Expand Search)
"client kepler algorithm" » "client server algorithm" (Expand Search)

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