The narrowly defined mixing configurations that have been examined so far are those that would be encountered in the process of mixing from a single black-white initial condition, either by the LS method or the NN approximation of the LS method. However, there are many other configurations to which LS mixing could be applied, such as other optimally mixed states (equal segment lengths) that the LS method does not produce (𝑁 ̸ = 0, 1, 3, 7, 15, 31), for example the 𝑁 = 2 configuration in Fig. . Other configurations, both similar and dissimilar to the training data, are also worth investigating. As before, we refer to the extension of the NN to configurations outside of its training repertoire as "extrapolation."
