Such maps are normally infinitely-dimensional, and in order to facilitate investigations of their properties, especially in the context of applications, finite-dimensional approximations have been proposed. The most commonly used one is known as the local structure theory, developed by H. Gutowitz et al. in 1987. In spite of the popularity of this approximation in CA research, examples of rigorous evaluations of its accuracy are lacking. In an attempt to fill this gap, we construct a local structure approximation for rule 14, and study its dynamics in a rigorous fashion, without relying on numerical experiments. We then compare the outcome with known exact results. %G English %Z TC 1 %Z WG 1.5 %2 https://inria.hal.science/hal-01824874/document %2 https://inria.hal.science/hal-01824874/file/469010_1_En_4_Chapter.pdf %L hal-01824874 %U https://inria.hal.science/hal-01824874 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-TC1 %~ IFIP-WG1-5 %~ IFIP-AUTOMATA %~ IFIP-LNCS-10875
