Consider the discrete Hopfield model investigated in Example 5. Test the vector x7 = (−1,−1, 1, 1, 1)T , update in the following orders, and determine to which vector the algorithm converges:

(a) x3(1), x4(1), x5(1), x2(1), x1(1);

(b) x1(1), x4(1), x3(1), x2(1), x5(1);

(c) x5(1), x3(1), x2(1), x1(1), x4(1);

(d) x3(1), x5(1), x2(1), x4(1), x1(1).
