 For any \(g\) in \(D(B)\), we let \(u(g, h_{j})\) be the epistemic utility of accepting \(g\) if \(h_{j}\) is true. We also assume that a rational probability measure \(P\) is associated with language \(L\), so that each \(h_{j}\) can be assigned with its epistemic probability \(P(h_{j}\mid e)\) given evidence \(e\). Then the best hypothesis in \(D(B)\) is the one \(g\) which maximizes the expected epistemic utility
