“…Below, we analyse the conditions under the same threshold and different () si score arrays. The above score array { () si } = {s(0), s(1), ⋯, s(4), s (5), s (6), s (7), s(8)} = {0, 10, 30, 60, 90, 120, 150, 180, 210} is increasing, but it is increasing irregularly. Now, we analyse other three regular increments, that is, () si is a function value.…”
