Line search convergence tolerance
NettetThis tolerance modification is not applied when the quasi-Newton method is used, since it is normal for this method to require a larger number of iterations to converge. You can … Nettetvarious parameters and customized routines (e.g., specialized line search variants), prescribe the convergence tolerance, and set monitoring routines. With this routine the user can also control all linear solver options in the KSP, and PCmodules, as discussed in KSP: Linear System Solvers.

NettetWhere the convergence tolerance of iterations was set to 0 ( setTol (0.0)) The Spark documentation state: "Smaller value will lead to higher accuracy with the cost of more iterations. Default is 1E-6. " But once changing the setter to setTol (0.1) the line search error doesn't occur anymore. NettetTitle: convergence of line search Methoch Created Date: 1/25/2024 7:17:19 PM
NettetIn ansys there are four convergence criteria (force, displacement, moment and rotation). When you use one of them, you may specify a value, a tolerance and a minimum reference.

Nettet4.2.2 Convergence of general line search methods In the following, we will analyse the convergence of general line search method (4.3). Of course, we cannot choose arbitrary αk,pk and still expect convergence. First of all, we would like to maintain the Armijo condition of Lemma 4.6: f(xk +αkpk)−f(xk) ≤c indigenous office designNettetAt every step of the backtracking line search, the trial step size is reduced by this factor.
