“…For example, consider EV a with MI = 120, r = 14, s = 30, and r-s = (14,30). Initially, K rs = { (14,20), (20,6), (6,26), (26,27), (27,30)}, D rs = 110 km, thus D rs < MI. However, the set of paths through the OD pair changed under road-block to K' rs = { (14,20), (20,6), (6,7), (7,8), (8,26), (26,27), and (27, 30)}, D' rs = 135 km, thus D' rs > MI.…”
