%description
An approximate Bayesian method for inferring Directed Acyclic Graphs
(DAGs) for continuous, discrete, and mixed data. The algorithm can use the
graph inferred by another more efficient graph inference method as input;
the input graph may contain false edges or undirected edges but can help
reduce the search space to a more manageable size. A
Metropolis-Hastings-like sampling algorithm is then used to infer the
posterior probabilities of edge direction and edge absence. References:
