Struct InformationStructure 

pub struct InformationStructure {
    pub sets: Vec<InformationSet>,
    pub node_to_set: HashMap<NodeId, usize>,
}

Collection of all information sets in a game.

Fields

sets: Vec<InformationSet>

Information sets indexed by their ID.

node_to_set: HashMap<NodeId, usize>

Map from node ID to information set ID.

Implementations

impl InformationStructure

pub fn new() -> Self

Create a new empty information structure.

pub fn add_set( &mut self, player: usize, nodes: Vec<NodeId>, actions: Vec<String>, ) -> usize

Add an information set.

pub fn set_for_node(&self, node: NodeId) -> Option<&InformationSet>

Get the information set for a node.

pub fn same_set(&self, a: NodeId, b: NodeId) -> bool

Check if two nodes are in the same information set.

pub fn validate(&self, tree: &GameTree) -> Result<(), String>

Validate that an information structure is consistent with a game tree.

Checks that:

• All nodes in a set belong to the same player
• All nodes in a set have the same number of actions
• No node appears in multiple sets
