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