For notational convenience, we define β(R) = 1 − C bi (R) and δ(R) = bi (R)di , i resulting in ζ1 (R) = β(R) R + Cδ(R). Furthermore, β(0) = 1 − nC and increases by jumps of size (multiples of) C to reach 1 when R = dn . Hence the minimum R∗ is located at the distance di for which β jumps above zero. These considerations allow us to mirror the conclusions we obtained for the original cost function: 1. The optimal value of R∗ coincides with one of the distances di which means that the optimal circle passes through at least one of the data points.

More precisely, for each point they introduce a variable ξi ≥ 0 such that xi − a 2 ≤ R2 + ξi . (2) This relaxation of the constraints is then offset by adding a penalty term to the cost function: n ζ(R, a, ξ) := R2 + C ξi . i=1 The constant C is a (pre-defined) unit cost that governs the trade-off between the size of the sphere and the number of outliers. After these modifications the authors in [8,4] arrive at the following constrained optimization problem: given n data points x1 , . . t. ∀i = 1, .

J. Pauwels and O. Ambekar The collection of all subgradients at a point x is called the subdifferential of f at x and denoted by ∂f (x). Notice that the subdifferential is a set-valued function! e. ∇f (x∗ ) = 0) can be generalized to non-differentiable functions as: 0 ∈ ∂f (x∗ ). e. set-valued) (23) ⎪ ⎩ 1 if x > 0 as at x = 0 any straight line with slope between 0 and 1 will be located under the graph of the ramp function. e. set-valued) (24) ⎪ ⎩ 0 if x < 0 To forestall confusion we point out that, unlike when used as a distribution, this definition of the Heaviside function insists its value at the origin is between zero and one.
