Perhaps you should try some spelling variations:
twisting algorithm » boosting algorithm (Expand Search), mining algorithm (Expand Search), tracking algorithm (Expand Search)
sampling algorithm » mining algorithm (Expand Search)
element twisting » element within (Expand Search)
element sampling » sediment sampling (Expand Search), element mapping (Expand Search), client sampling (Expand Search)

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

• Removing quotes may allow a broader search: (( element twisting algorithm ) OR ( element sampling algorithm )).
