Using automatic differentiation in the optimization of XIAMEN software. (Chinese. English summary) Zbl 1199.65066

Summary: Compared to the finite difference method, the automatic differentiation method has significant advantage in terms of the running time and the computational precision. By using the adjoint model to calculate gradients, the XIAMEN software is optimized with apparent speedup. The ADG software is used to automatically generate the adjoint model, which dramatically reduces the labors and the difficulty of the implementation process. Several related techniques are discussed and several testing results are presented.
