Computer science description: In this report we provide some technical details for some of the results appeared in [Alessio et al.(2005)]. 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. publisher: University of Siena date: 2005 type: Working Paper type: NonPeerReviewed format: application/pdf language: en identifier: http://eprints.imtlucca.it/2251/1/TR_Bemporad_2005_UNISI.pdf identifier: Alessio, Alessandro and Bemporad, Alberto and Addis, B. and Pasini, Alessandro An algorithm for PWL approximations of nonlinear functions.
