Rapid Determination of Geoacoustic Properties of the Sea Floor by Simulated Annealing

Abstract

The Naval Research Laboratory (NRL) developed and tested a simulated annealing (SA) inversion method for geoacoustic data. Significant improvements in the classical Metropolis SA algorithm improved the speed and accuracy of the SA method. This method solves for compressional and shear wave velocities, layer thicknesses, density, and attenuation when the data are sensitive to these properties. NRL demonstrated the effectiveness of the SA method with a realistic geological case that is a nonlinear problem with several traps that foil other inversion methods. Simulated annealing.
