英文摘要In this paper, we derive a random-enhanced quantum particle swarm optimization (QPSO) algorithm and develop a new finite difference (FD) scheme based on this algorithm. The random-enhanced QPSO algorithm has advantages of convergence speed and can converge within the 200th iteration. Under the same conditions, the convergence speed of the conventional QPSO algorithm is much lower than that of the random-enhanced QPSO algorithm. Numerical dispersion analysis reveals that the optimized FD scheme based on the random-enhanced QPSO algorithm has a broader spectral coverage, and the accuracy error is maintained within a valid range, signifying that the random-enhanced QPSO algorithm can better search for accurate global solutions. Finally, numerical modeling of elastic wave equations is performed using the optimized FD scheme based on the random-enhanced QPSO algorithm. The numerical modeling results indicate that the optimized FD scheme based on the random-enhanced QPSO algorithm can effectively suppress numerical dispersion.
