In the first section we provide the proof of continuity of the PPWA function computed with the ”squaring the circle” algorithm stated in ACC 06. Then, we analyze the complexity of the previous algorithm, in terms of the desired level of accuracy in the approximation of the PPWA function. date: 2005 number: publisher: University of Siena pages: 8 institution: IMT Institute for Advanced Studies Lucca citation: Alessio, Alessandro and Bemporad, Alberto and Addis, B. and Pasini, Alessandro An algorithm for PWL approximations of nonlinear functions.
