Doubts about the section "Simulation"

I am not sure if the section "Simulation" contains true information. For sure there are not enough references to the literature there. The Nature article [8] is unfortunately very sparse on details and explanations. Moreover I don't know what is the source of equation in "Snap, crackle and pop". The regime "snapping to equilibrium" seems fishy, shouldn't it be "much greater" not "much lesser"?

I tried making a simulation based on the model presented. It does not seem to work as it should. The Nature article deals with 3D case; here 2D case is described. Taking 4 neighbors in 2D case seems to cause numerical artifacts. The cells get divided into odd and even indices with weak interaction which leads to checkerboard like solutions. It may be that it does not matter for the range of parameters considered in the animation but they are not given. This artifact can be removed easily by assuming that spin is its own neighbor too or if diagonal cells are neighbors too. — Preceding unsigned comment added by Tablis (talk • contribs) 14:17, 14 June 2022 (UTC)[reply]
