Perhaps you should try some spelling variations:
computations using » computation using (Expand search), populations using (Expand search), computations in (Expand search)
by computations » by computational (Expand search), of computations (Expand search), by computacional (Expand search)
coding pitons » loading pistons (Expand search)
using coding » using coping (Expand search), using coating (Expand search), using cooking (Expand search)
pid program » aid program (Expand search), phd program (Expand search), pibid program (Expand search)
using pid » using rapid (Expand search), using lipid (Expand search), tuning pid (Expand search)

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

• Removing quotes may allow a broader search: (( by computations using pid program ) OR ( using coding pitons python programming ))*.
