StandardBrownianNode Class Reference

#include <Node.h>

List of all members.


Detailed Description

Nodes in a stochastic lattice for a standard Brownian motion Z. Emphasis is on smallest possible memory footprint. Nodes only store the array of edges and the state k of the Brownian motion

as a integer multiples of the tick size a. Nodes don't need to know anything else, not at which time they live nor even which lattice they live in. The lattice knows that and all else such as the transition probabilities. This avoids storing the same data in each of the million nodes in the lattice.
