Hopsy.round moves the chebyshev center

[ronald-jaepel]

Here's the example case we just discussed:

problem = hopsy.Problem(
    A=np.array(
        [[1., 1.],
         [-1., -0.],
         [-0., -1.],
         [1., 0.],
         [0., 1.]]
    ),
    b=np.array(
        [1., -0., 0.5, 1., 2.]
    )
)
print(hopsy.compute_chebyshev_center(problem, original_space=True)[:, 0])
problem = hopsy.round(problem)
print(hopsy.compute_chebyshev_center(problem, original_space=True)[:, 0])
