bles. Each slack variable
            corresponds to an inequality constraint. If the slack is zero,
            the corresponding constraint is active.
        con : 1-D array
            The (nominally zero) residuals of the equality constraints,
            that is, ``b - A_eq @ x``
        phase : int
            The phase of the optimization being executed. In phase 1 a basic
            feasible solution is sought and the T has an additional row
            representing an alternate objective function.
        status : int
            An integer representing the exit status of the optimization::

                 0 : Optimization terminated successfully
                 1 : Iteration limit reached
                 2 : Problem appears to be infeasible
                 3 : Problem appears to be unbounded
                 4 : Serious numerical difficulties encountered

        nit : int
            The number of iterations performed.
        message : str
            A string descriptor of the exit status of the optimization.
postsolve_args : tuple
    Data needed by _postsolve to convert the solution to the standard-form
    problem into the solution to the original problem.
maxiter : int
    The maximum number of iterations to perform before aborting the
    optimization.
tol : float
    The tolerance which determines when a solution is "close enough" to
    zero in Phase 1 to be considered a basic feasible solution or close
    enough to positive to serve as an optimal solution.
phase : int
    The phase of the optimization being executed. In phase 1 a basic
    feasible solution is sought and the T has an additional row
    representing an alternate objective function.
bland : bool
    If True, choose pivots using Bland's rule [3]_. In problems which
    fail to converge due to cycling, using Bland's rule can provide
    convergence at the expense of a less optimal path about the simplex.
nit0 : int
    The initial iteration number used to keep an accurate iteration total
    in a two-phase problem.

Returns
-------
nit : int
    The number of iterations. Used to keep an accurate iteration total
    in the two-phase problem.
status : int
    An integer representing the exit status of the optimization::

     0 : Optimization terminated successfully
     1 : Iteration limit reached
     2 : Problem appears to be infeasible
     3 : Problem appears to be unbounded
     4 : Serious numerical difficulties encountered
