Exploring the causal order of binary variables via exponential hierarchies of Markov kernels
Abstract. We propose a new algorithm for estimating the causal structure that underlies the observed dependence among n (n ≥ 4) binary variables X1, . . . , Xn. Our inference pri...

Hierarchies and Characterizations of Stateless Multicounter Machines
Abstract. We investigate the computing power of stateless multicounter machines with reversal-bounded counters. Such a machine can be deterministic, nondeterministic, realtime (the...
