Using Adaptive Simulated Annealing to Estimate Ocean Bottom Acoustic Properties from Acoustic Data

Abstract

The Phase I work goal was the reduction in run times for both transmission loss and bottom scatter acoustic inversion codes. The reduction in run times was accomplished using a recently developed variant of the Simulated Annealing (SA) family of non-linear inversion algorithms called Adaptive Simulated Annealing (ASA), which can be significantly faster than conventional forms of simulated annealing. The replacement of the Fast Annealing (FA) algorithm by the ASA algorithm in PSI's TL inversion code has resulted in run times between 12 and 16 times shorter accompanied by an improved fit between the predicted and measured transmission loss data.
