   元胞自动机：森林火灾模型 规则： (1)正在燃烧的树变成空格位； (2)如果绿树格位的最近邻居中有一个树在燃烧，则它变成正在燃烧的树； (3)在空格位，数以概率p生长； (4)在最近的邻居中没有正在燃烧的树的情况下树在每一时步以概率f(闪 电)变为正在燃烧的树。( Cellular Automata: Forest Fire model Rule: (1) burning of trees into a space bit (2) If the tree can notably nearest neighbor has a tree in the burning, then it turned into being burning tree (3) in the space bit, a few with probability p growth (4) In the nearest neighbor is not burning under the tree the tree in each time step with probability f (flash electricity) Variable for the burning trees.)
