crystallographic group

The modified constrained simplex algorithm uses Lyapunov exponents to estimate initial iterating points in dynamic plane and construct general M sets of the crystallographic group through the dynamic characters of these points reflecting.

针对逃逸时间算法计算量大,构图时间长的特点,本文提出了改进的有约束的单纯形最优化方法,求解了使平面结晶体群映射的Jacobin矩阵|DF|=0的点集作为初始迭代点集,由Lyapunov指数判定初始迭代点集的动力学特性,构造了平面结晶体群动力系统的广义M集。
