Full Waveform Inversion using Derivative-Free Optimization hybrid strategy
Conference Paper
Full-text available
  • Aug 2019
The Full Waveform Inversion (FWI) is an accurate approach for finding high resolution velocity models because it uses all information present in the wavefield. The FWI traditionally employs gradient-based algorithms. Most of these algorithms are of high computational cost and have precision limited to local minima. Derivative-Free Optimization (DFO...
