Abstract:
Full waveform inversion is mainly used to obtain high resolution velocity models of subsurface�� The size of full waveform inversion will lead to a gigantic computation cost�� Under the available computer resource and the limitation of full waveform inversion��the authors propose L-BFGS algorithm as the optimization method to solve this problem�� In order to demonstrate the flexibility of the method��three different numerical experiments have been done to analyze the properties of full waveform inversion based on L-BFGS�� |
