The identity problem for matrix semigroups in SL(2, Z) is NP-complete. In Proceedings of Symposium on Discrete Algorithms 2017, 2017.P. C. Bell, M. Hirvensalo, and I. Potapov. The identity problem for matrix semigroups in SL2(Z) is NP-complete. In Proceedings of the Annual ACM...
In the above exercise - matrix = np.identity(3): This creates a 3x3 identity matrix using the np.identity() function from NumPy. An identity matrix is a square matrix with 1's along the diagonal and 0's everywhere else. vert_stack = np.vstack((matrix, matrix, matrix)): This uses ...
