Abstract
We propose a restarting technique for the nonlinear conjugate gradient (NCG) method in solving the inverse problem of parameter identification in elliptic systems. The technique can enhance the performance of the NCG method in a certain generic situation. We conduct extensive numerical experiments to compare the performance of five well-known conjugate gradient schemes by incorporating the restarting technique. Numerical results show the efficiency and stable performance of the restarted NCG schemes. The smoothing property of the proposed method is also investigated, which could be employed in the multigrid solver for inverse problems.
