Public Member Functions | |
virtual bool | InitializeImpl (const OptionsList &options, const std::string &prefix) |
Implementation of the initialization method that has to be overloaded by for each derived class. | |
virtual bool | InitializeSolve () |
Method for initializing for the next iterative solve. | |
virtual ETerminationTest | TestTermination (Index ndim, const Number *sol, const Number *resid, Index iter, Number norm2_rhs) |
This method checks if the current soltion of the iterative linear solver is good enough (by returning the corresponding satisfied termination test), or if the Hessian should be modified. | |
virtual void | Clear () |
This method can be called after the Solve is over and we can delete anything that has been allocated to free memory. | |

This method checks if the current soltion of the iterative linear solver is good enough (by returning the corresponding satisfied termination test), or if the Hessian should be modified.
The input is the dimension of the augmented system, the current solution vector of the augmented system, the current residual vector.
