Let each site of the square latticebe independently assigned one of three states: atrapwith probabilityp, atargetwith probabilityq, andopenwith probability, where. Consider the following game: a token starts at the origin, and two players take turns to move, where a move consists of moving the token from its current sitexto eitheror. A player who moves the token to a trap loses the game immediately, while a player who moves the token to a target wins the game immediately. Is there positive probability that the game isdrawnwith best play—i.e. that neither player can force a win? This is equivalent to the question of ergodicity of a certain family of elementary one-dimensional probabilistic cellular automata (PCA). These automata have been studied in the contexts of enumeration of directed lattice animals, the golden-mean subshift, and the hard-core model, and their ergodicity has been noted as an open problem by several authors. We prove that these PCA are ergodic, and correspondingly that the game onhas no draws. On the other hand, we prove that certain analogous gamesdoexhibit draws for suitable parameter values on various directed graphs in higher dimensions, including an oriented version of the even sublattice ofin all. This is proved via a dimension reduction to a hard-core lattice gas in dimension. We show that draws occur whenever the corresponding hard-core model has multiple Gibbs distributions. We conjecture that draws occur also on the standard oriented latticefor, but here our method encounters a fundamental obstacle.
