摘要：
In this paper, a new interpolation operator is designed basin on red-black coarsening. Combining the interpolation operator, a cascadic algebraic two-grid (CATG) method and a cascadic algebraic two-level (CATL) method for the elliptic problems of second order are presented. Numerical experiments show that the better approximate value is obtained without smoothing on finer level, and the new methods reduce computational cost.
