## Node

The nodes are one of the basics in constructing a Hugin Bbn or influence diagram. Currently, Hugin has four types of nodes different in their look and semantics.

- Discrete Chance Nodes - represent random variables with a discrete finite state space.
- Continuous Chance Nodes - represent random variables with a continuous infinite satet space having a Gaussian normal distribution.
- Decision Nodes - represent decisions or actions with a discrete state space.
- Utility Nodes - represent the utility function one or more decisions are to be compared on.

The graph of a Bbn/influence diagram consist of the nodes and the links.
