Package de.labathome.trustconstr.records

Class CGInfo

java.lang.Object

de.labathome.trustconstr.records.CGInfo

public class CGInfo
extends Object

Result of a projected-CG inner solve from QPSubproblem.projectedCG(de.labathome.trustconstr.interfaces.LinearOperator, de.labathome.trustconstr.matrix.Matrix, java.lang.Object, java.lang.Object, de.labathome.trustconstr.matrix.Matrix). Carries the solution vector, iteration count, why CG terminated, optionally the full iterate trajectory, and a flag indicating whether the proposed step landed on the trust-region boundary.
