Perhaps you should try some spelling variations:
tracking algorithm » learning algorithm (Expand Search), processing algorithm (Expand Search)
mapping algorithm » sampling algorithm (Expand Search), matching algorithm (Expand Search), mining algorithm (Expand Search)
elements tracking » movement tracking (Expand Search)
element mapping » elemental mapping (Expand Search), element modeling (Expand Search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( element mapping algorithm ) OR ( elements tracking algorithm ))~.
