Accelerating full waveform inversion using HSS solver and limited memory conjugate gradient method

Full waveform inversion (FWI) consists in finding an accurate optimal model of the subsurface from local measurements of the seismic wavefield. This aim is achieved by minimizing the difference between the observed and predicted data, starting from an initial estimation of the subsurface parameters....
