- The domain is divided twice in two-grid method.At first, divide the domain into coarse gird.A nonlinear problem is solved on this coarse grid. 两重网格算法是先在粗网格上计算一个非线性问题,然后将粗网格细分,再在细网格上计算一个线性问题。
- Using coarse grids can improve calculative efficiency. 采用粗网格可以提高计算效率。
- So in this paper, we use a much more robust algorithm, Hooke-Jeeves pattern search method, to solve the problem on the coarse grid, and the faster method: Polack-Ribiere conjugate gradient method or SSC gradient method on the finer grid. 故在本文中采用更为健壮的Hooke-Jeeves模式搜索法在粗网格上进行求解，得到一个较好的初值，然后再采用速度较快Polack-Ribiere共轭梯度法或不含线搜索的SSC梯度法在细网格上进行磨光，这样既保证了方法的收敛，又保证了速度。
