Consider the set $Q$ and denote its Chebyshev center by $\backslash hat$. $\backslash hat$ can be computed by solving: : $\backslash min\_\; \backslash max\_\; \backslash left\backslash |\; x\; -\; \backslash hat\; x\; \backslash right\backslash |^2.$ Despite these properties, finding the Chebyshev center may be a hard numerical optimization problem. For example, in the second representation above, the inner maximization is non-convex if the set ''Q'' is not convex. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chebyshev center」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
