    • hasMaxPrimalRayInfeasibility

      public boolean hasMaxPrimalRayInfeasibility()
       Let x_ray be the algorithm's estimate of the primal extreme ray where x_ray
 is a vector that satisfies the sign constraints for a ray, scaled such that
 its infinity norm is one (the sign constraints are the variable bound
 constraints, with all finite bounds mapped to zero). A simple and typical
 choice of x_ray is x_ray = x / | x |_∞ where x is the current primal
 iterate projected onto the primal ray sign constraints. For this value
 compute the maximum absolute error in the primal linear program with the
 right hand side set to zero.
      optional double max_primal_ray_infeasibility = 1;
      Specified by:

      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 (satisfying the dual variable
 constraints) scaled such that its infinity norm is one. A simple and

 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

 compute the maximum absolute value of the constraint error for
