The key convergence result is proved using a fundamental property of informational divergence. As a ... WebbShannon’s information-theoretic lower bound has been developed for uniquely decodable systems of bit strings, while ordinary data structures often consist of many separate blocks of memory. One might expect that adapting the bound to data structures is trivial, but we demonstrate that this is not the case. small bathroom refit
