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