  1. The columns (\(N_0\), N, \(N_2\), \(N_g\)) describe the problem setup. The next three columns indicate the results for the proposed method. The next three columns indicate the results for the exact method compared against. The first “Time (s)” column contains the execution time for CPU and GPU, in the form. The second ``Time (s)" column contains the execution time for the other method. Values followed by (E) were extrapolated from previous running times.
