◆ NodeId

using bncore::NodeId = typedef std::uint32_t

Handle of a variable within one Graph.

Graph::add_variable() assigns ids in insertion order starting at 0, so an id is also the variable's index in the graph and its column in a hard evidence matrix (see BatchExecutionEngine::evaluate_multi()).
