Calculates properties of a Bayesian network or Dynamic Bayesian network when converted to a tree for inference.

This is done without requiring the memory to actually perform inference, and so can be useful to test whether exact inference is feasible on a network, or determine memory requirements.

This can be done while taking into account any evidence currently set, and the particular queries that are being requested.

Parameters:

network - The Bayesian network or Dynamic Bayesian network.

queryDistributions - The distributions being queried.

evidence - Any evidence.

queryOptions - Options which affect how the query is performed.

Returns:

Information about the tree, such as tree width.
