class pygambit.gambit.HistoryIndexedVector#

A read-only mapping from a node’s History to a computed value, one entry per node.

Unlike PlayerIndexedVector/StrategyIndexedVector, which are keyed by a stable label, this is keyed by the node’s own History – unique to that node – since the value can genuinely differ between two nodes, even nodes belonging to the same information set.
