Let $x_n$ be a reinforced random walk which satisfy the following recursion: $x_0 = 0$ and $$ x_n = (1 + \alpha) x_{n-1} + \alpha \epsilon_n $$ for some $\alpha 0$, $\epsilon_n$ is arbitrary. Abstract = to a given finite graph we associate three kinds of adic, or bratteli-vershik, systems: stationary, symbol-count, and reinforced. Biological systems that build transport networks, such as trail-laying ants and the slime mould physarum , can be described in terms of reinforced random walks in a reinforced random walk, the route taken by 'walking' particles depends on the previous routes of other particles here, we present a novel form of random walk in which the flow.

We will explain how the edge-reinforced random walk, introduced by coppersmith and diaconis in 1986, is related to models in statistical physics, namely the supersymmetric hyperbolic sigma model studied by disertori, spencer and zirnbauer (2010), the random schrödinger operator and dynkin's isomorphism.
