摘要: Chapter 3 is devoted to studying the computation efficiency of existing methods for computing focus values. Three typical methods, namely Poincare method or Takens method, perturbation technique, and singular point value are discussed. These three shown have same order computational complexity; no has been developed so far ‘minimal values’.
