      • hasMaxPrimalRayInfeasibility

        public boolean hasMaxPrimalRayInfeasibility()
         Let x_ray be the algorithm's estimate of the primal extreme ray where x_ray
 is a vector scaled such that its infinity norm is one. A simple and typical
 choice of x_ray is x_ray = x / | x |_∞ where x is the current primal
 iterate. For this value compute the maximum absolute error in the primal
 linear program with the right hand side and finite variable bounds set to
 zero. This error refers to both the linear constraints and sign constraints
 on the ray.

        hasMaxPrimalRayInfeasibility in interface SolveLogOuterClass.InfeasibilityInformationOrBuilder
        Returns:
        Whether the maxPrimalRayInfeasibility field is set.

      • hasMaxDualRayInfeasibility

        public boolean hasMaxDualRayInfeasibility()
         Let (y_ray, r_ray) be the algorithm's estimate of the dual and reduced cost
 extreme ray where (y_ray, r_ray) is a vector scaled such that its infinity
 norm is one. A simple and typical choice of y_ray is
 (y_ray, r_ray) = (y, r) / max(| y |_∞, | r |_∞) where y is the
 current dual iterate and r is the current dual reduced costs.
 Consider the quadratic program we are solving but with the objective (both
 quadratic and linear terms) set to zero. This forms a linear program
 (label this linear program (1)) with no objective. Take the dual of (1) and
 compute the maximum absolute value of the constraint error for
 (y_ray, r_ray) to obtain the value of max_dual_ray_infeasibility.
        optional double max_dual_ray_infeasibility = 4;
        Specified by:
        hasMaxDualRayInfeasibility in interface SolveLogOuterClass.InfeasibilityInformationOrBuilder
        Returns:
