Chebyshev center

In geometry, the Chebyshev center of a bounded set having non-empty interior is the center of the minimal-radius ball enclosing the entire set , or alternatively (and non-equivalently) the center of largest inscribed ball of . In the field of parameter estimation, the Chebyshev center approach tries to find an estimator for given the feasibility set , such that minimizes the worst possible estimation error for x (e.g. best worst case).
