Lorenz说：“在巴西的蝴蝶拍打翅膀会引发德克萨斯州的一场龙卷风吗？”，就是“蝴蝶效应”，是由三维常微分方程组描述的，本算法用来计算蝴蝶效应("Does a butterfly flapping its wings in Brazil trigger a tornado in Texas?" Lorenz said" The butterfly effect is described by the three-dimensional ordinary differential equations. This algorithm is used to calculate the butterfly effec)
