Lauritzen and Spiegelhalter: local probability computation in graphical expert systems

What changed

Combined graph triangulation and local probability representations for exact evidence propagation.

Scientific scope

The record is the exact two-author 1988 JRSS B paper and its sparse-network propagation framework. It does not absorb all belief-propagation variants, later junction-tree software or every probabilistic graphical model.
