Improved particle swarm optimizer for solving parameters of Van Genuchten model
|
Abstract:
Van-Genuchten model is widely implemented when researching soil hydraulic characteristics. Its four parameters are the key to application of this model.In order to solve these parameters exactly, this paper presents an improved PSO based on dynamic neighbor topology and local search(DNLPSO) to solve these parameters.The algorithm shows the following characteristics:The neighborhood of each particle is dynamically changed in terms of the performances of the particles;the velocity of each particle is not adju...
