Optimal and near optimal quantization of integrable functions
A continuous function is approximated by step functions with given number of break points. The approximations are nonlinear. Local as well as global optimization strategies based on fixed-point analysis are integrated with branch and bound techniques for multivariate Lipschitz minimization. Branching strategies are based on the structure of attracting domains. (C) 2000 Elsevier Science Ltd. Ail rights reserved.
