Investigation on divisional inversion of dam mechanic parameters based on improved PSO algorithms

In order to inverse divisional mechanic parameters and overcome shortcomings of conventional Particle Swarm Optimization(PSO),improved PSO algorithms such as stretching objective function based PSO,Metropolis algorithm based PSO and adaptive algorithm based PSO were used and compared with Quantum Particle Swarm Optimization Algo rithm and catastrophic PSO.The case study showed that improved PSO was more effective than conventional PSO,and fit ted to inverse divisional mechanic parameters of dam.
