Seismic waveform tomography with shot-encoding using a restarted L-BFGS algorithm
Abstract In seismic waveform tomography, or full-waveform inversion (FWI), one effective strategy used to reduce the computational cost is shot-encoding, which encodes all shots randomly and sums them into one super shot to significantly reduce the number of wavefield simulations in the inversion.
