Comparisons are made between two types of restriction\: injection and full weighting. The used prolongation process is the trilinear interpolation. This work is concerned with the study of the influence of the smoothing value \(v\), number of mesh levels \(L\) and number of unknowns \(N\) on the CPU time, as well as the analysis of algorithm complexity."]
