One of the challenges in analyzing the strategies in contract bridge stems from the fact that it is a Bayesian game with a very large type space, and that players’ action sets depend on their type. This results in a the strategy space being of a size where brute force methods of analysis are not practical. We present a general approach to simplifying this strategy space through the use of equiv...

Different directed acyclic graphs (DAGs) may be Markov equivalent in the sense that they entail the same conditional independence relations among the observed variables. Meek (1995) characterizes Markov equivalence classes for DAGs (with no latent variables) by presenting a set of orientation rules that can correctly identify all arrow orientations shared by all DAGs in a Markov equivalence cla...
