DIC variations with respect to the optimal DIC value (${\mathrm{DIC}}_{\mathit{opt}}=1666.25$), yielded by different combinations of the neighborhood matrices $C_1$ and $D_5$ a, $C_1$ and F b, and $C_1$ and S c, considering different values of the weight s (from 0.1 to 0.9, in intervals of 0.1), and several thresholds of u (0, 0.01, 0.05, and 0.10) for determining the negligible neighbors
