Perhaps you should try some spelling variations:
matching algorithm » mining algorithm (Expand Search), sampling algorithm (Expand Search), tracking algorithm (Expand Search)
modeling algorithm » mining algorithm (Expand Search), sampling algorithm (Expand Search), boosting algorithm (Expand Search)
element matching » element mapping (Expand Search), employment matching (Expand Search), element within (Expand Search)
element modeling » element modelling (Expand Search), element model (Expand Search)

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

• Removing quotes may allow a broader search: (( element matching algorithm ) OR ( element modeling algorithm ))*.
