In this paper, a computer program for determining near earthquake time and space parameters is designed, on the basis of memorygradientmethod for unconstrained optimization.

The conjugate gradientmethod (CGM) and fast Fourier transform (FFT) technique are used to reduce the necessary memory and CPU time.
In chapter 4, a implementation version is given for the trust region gradientmethod with memory model. Numerical results show that this scheme is feasible.
