Uses of State in de.labathome.trustconstr

Methods in de.labathome.trustconstr that return State

Modifier and Type	Method	Description
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).
