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