W e compare four graphical techniques for representation and solution of asymmetric decision problems-decision trees, influence diagrams, valuation networks, and sequential decision diagrams. We solve a modified version of Covaliu and Oliver's Reactor problem using each of the four techniques. For each technique, we highlight the strengths, weaknesses, and some open issues that perhaps can be resolved with further research. In this section, we describe a DT representation and solution of a

... asymmetric decision problem called the Reactor problem, and we discuss strengths, weaknesses, and some open issues associated with DTs. The Reactor problem is a modified version of the problem described by Covaliu and Oliver (1995) . In our version, Bayesian revision of probabilities is re-
