![]() | Sikorski, Kris | Selected fixed point problems and algorithms | We present a new version of the almost optimal Circumscribed Ellipsoid Algorithm (CEA) for approximating fixed points of nonexpanding Lipschitz functions. We utilize the absolute and residual error criteria with respect to the second norm. The numerical results confirm that the CEA algorithm is m... | Fixed point problems; Optimal algorithms; Nonlinear equations; Ellipsoid algorithm; Computational complexity. | 2007 |
