Bases:
PyAMGXSolverThe ClassicalAMGSolver is an interface to the classical AMG solver in AMGX, with a Jacobi smoother by default.
- Parameters:
tolerance (
float) – Required error tolerance.criterion (
{'default', 'unscaled', 'RHS', 'matrix', 'initial', 'legacy'}) – Interpretation oftolerance. See Convergence for more information.iterations (
