Definition. Bounded utility perturbation [ftip-00G3]
On a common finite outcome law \(\mathsf Q\), let each artifact \(M\) have score maps \(s_M,t_M:\mathcal Z\to [0,1]\). They have perturbation radius \(\varepsilon =\sup _{M,\,z\in \operatorname {supp}(\mathsf Q)} |s_M(z)-t_M(z)|\) when \(0\leq \varepsilon \leq 1\); write \(J_s(M)=\mathbb E_{\mathsf Q}[s_M]\) and \(J_t(M)=\mathbb E_{\mathsf Q}[t_M]\).
