Perhaps you should try some spelling variations:
modeling algorithm » mining algorithm (Expand Search), sampling algorithm (Expand Search), matching algorithm (Expand Search)
elements sampling » sediment sampling (Expand Search), element mapping (Expand Search)
element modeling » element modelling (Expand Search), element model (Expand Search)
client sampling » sediment sampling (Expand Search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"element modeling algorithm\\") OR (\\"((elements sampling) OR (client sampling)) algorithm\\"))\"".
• Removing quotes may allow a broader search: (( element modeling algorithm ) OR ( ((elements sampling) OR (client sampling)) algorithm )).
