Perhaps you should try some spelling variations:
"elements matching algorithm" » "elements sampling algorithm" (Expand Search), "elements tracking algorithm" (Expand Search), "elements within algorithm" (Expand Search), "element mapping algorithm" (Expand Search)
"client mining algorithm" » "client learning algorithm" (Expand Search), "client means 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)

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: "((((\"client mining algorithm\") OR (\"client needs algorithm\"))) OR (\"elements matching algorithm\"))~".
• Removing quotes may allow a broader search: (((( client mining algorithm ) OR ( client needs algorithm ))) OR ( elements matching algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("client mining algorithm") OR ("client needs algorithm"))) OR ("elements matching algorithm"))*.
