Abstract A new method of optimal discretization is proposed in order to solve the illconditioned problem caused by inefficient discretization approaches. The artificial fishswarm algorithm is used to optimize the objective function converted by the problem of dividing the segmental points. The virtual segmental points are introduced to effectively combine the discrete intervals based on the swarm deed of fishswarm algorithm. The case analysis shows that the number of the discrete intervals is small. Furthermore, the decision rules derived from the proposed method are simple and with fine robustness.
