Random generation of Influence Diagrams

class pyagrum.IDGenerator

IDGenerator is used to easily generate influence diagrams.

IDGenerator() -> IDGenerator : default constructor

generate(nbrNodes=10, arcDensity=0.2, chanceNodeDensity=0.8, utilityNodeDensity=0.1, max_modality=2)

Generate a new influence diagram given the parameters.

• Parameters:
  • nbrNodes (int) – the number of node
  • arcDensity (float) – the density of arc (1 for a complete graph)
  • chanceNodeDensity (float) – the density of chance node
  • utilityNodeDensity (float) – the density of utility node
  • max_modality (int) – the maximum value for modalities
• Returns: the generated influence diagram
• Return type: InfluenceDiagram
