mu
This is the warm start value for the barrier penalty parameter.

scale_f
This is the cppad_mixed scaling factor for the ipopt objective function @(@ f(x) @)@.

x_info
If the size of this vector is zero, the size of g_info must also be zero. Otherwise, x_info has size equal to the number of primal variables @(@ x @)@. The j-th element of this vector contains the following fields:

x
is the warm start value for x[j].

z_L
is the warm start value for z_L[j].

z_U
is the warm start value for z_U[j].

scale_x
is the cppad_mixed scaling factor for x[j].

g_info
If the size of x_info is non-zero, g_info has size equal to the number of @(@ g(x) @)@ constraints. The i-th element of this vector contains the following fields:

lambda
is the warm start value for lambda[i].

scale_g
is the cppad_mixed scaling factor for @(@ g_i(x) @)@.

This structure is part of the CppAD Mixed user API.
