| 英文摘要 | In the standard particle swarm optimization (PSO), the premature convergence of particles and slow convergence in the late process decrease the searching ability of the algorithm. In this paper, by taking the positions of the particles into consideration, we propose an improved parallel particle swarm optimization (IPPSO) algorithm, which can increase the efficiency, to reduce the blindness in the search process. The performance of this improved particle swarm optimization method in solving 2-D scalar wave equation inversion problems is investigated. Our numerical experiments indicate that this method is suitable for scalar velocity inversion problems since it has merits such as low dependence on initial model, high constringency speed, stable result and strong antinoise ability. The results hold promise for further elastic wave equation and elastic parameters inversion studies. |
