Uses of CGInfo in de.labathome.trustconstr

Methods in de.labathome.trustconstr that return CGInfo

Modifier and Type	Method	Description
static CGInfo	QPSubproblem.projectedCG(LinearOperator H, Matrix c, Object Z, Object Y, Matrix b)	Solve the equality-constrained quadratic program
static CGInfo	QPSubproblem.projectedCG(LinearOperator H, Matrix c, Object Z, Object Y, Matrix b, double trustRadius, double[] lb, double[] ub, double tolerance)	Solve EQP problem with projected CG method.
static CGInfo	QPSubproblem.projectedCG(LinearOperator H, Matrix c, Object Z, Object Y, Matrix b, double trustRadius, double[] lb, double[] ub, double tolerance, long maxIterations, long maxInfeasibleIterations, boolean returnAll)	Solve the equality-constrained quadratic program

Methods in de.labathome.trustconstr with parameters of type CGInfo

Modifier and Type	Method	Description
boolean	BarrierSubproblem.stoppingCriteria(State state, Matrix z, boolean lastIterationFailed, double optimality, double constrViolation, double trustRadius, double penalty, CGInfo cgInfo)	Stopping criterion for the barrier subproblem; mirrors formula (2.3) from Byrd-Hribar-Nocedal (1999), p.879.
static State	MinimizeTrustConstr.updateState(State state, Matrix x, boolean lastIterationFailed, ScalarFunction objective, PreparedConstraint[] preparedConstraints, long startTime, double trustRadius, double constraintPenalty, CGInfo cgInfo)	Refresh the equality-path State record after an outer iteration (the function value, gradient, optimality, constraint violation, trust-region and CG fields).
static StateIP	MinimizeTrustConstr.updateStateIP(StateIP state, Matrix x, boolean lastIterationFailed, ScalarFunction objective, PreparedConstraint[] preparedConstraints, long startTime, double trustRadius, double constraintPenalty, CGInfo cgInfo, double barrierParameter, double barrierTolerance)	Refresh the IP-path StateIP record after an outer iteration: delegates to MinimizeTrustConstr.updateState(de.labathome.trustconstr.records.State, de.labathome.trustconstr.matrix.Matrix, boolean, de.labathome.trustconstr.ScalarFunction, de.labathome.trustconstr.records.PreparedConstraint[], long, double, double, de.labathome.trustconstr.records.CGInfo) and then sets the barrier-specific fields.
