Sixth European Workshop on Probabilistic Graphical Models
Troubleshooting is one of the application areas of Bayesian networks. Given a probabilistic model of a malfunctioning device, the task is to find the repair strategy with minimal expected cost. Except for simple cases, finding an optimal strategy is NP-hard. We show that optimal troubleshooting strategies are also hard to approximate.
