A solution set $${\displaystyle (x,\Delta )}$$ for the RCC is also a solution for the CLS, and thus $${\displaystyle T\in V}$$. This means that the CLS estimate is the solution of a looser relaxation than that of the RCC. Hence the CLS is an upper bound for the RCC, which is an upper bound for the real Chebyshev center. See more In geometry, the Chebyshev center of a bounded set $${\displaystyle Q}$$ having non-empty interior is the center of the minimal-radius ball enclosing the entire set $${\displaystyle Q}$$, or alternatively (and non-equivalently) … See more Consider the case in which the set $${\displaystyle Q}$$ can be represented as the intersection of $${\displaystyle k}$$ ellipsoids. See more Since both the RCC and CLS are based upon relaxation of the real feasibility set $${\displaystyle Q}$$, the form in which $${\displaystyle Q}$$ is defined affects its relaxed versions. … See more There exist several alternative representations for the Chebyshev center. Consider the set $${\displaystyle Q}$$ and denote its Chebyshev center by $${\displaystyle {\hat {x}}}$$. $${\displaystyle {\hat {x}}}$$ can be computed by solving: See more It can be shown that the well-known constrained least squares (CLS) problem is a relaxed version of the Chebyshev center.
