Effective resistance random walks
WebA remarkably important random walk-based metric for mea-suring vertex similarity is the effective resistance. Given a graph treated as a resistor network, the effective resistance ( , ) between two vertices , in is the energy dissipation in the net-work when routing one unit of current from to . It is well known http://cs.yale.edu/homes/spielman/462/2007/lect8-07.pdf

WebA simple random walk is then a random walk on a network with unit edge weights. More precisely, a random walk on a network [G;c] is a Markov chain on state space V(G) with … Webwe get an effective resistance R satisfying 1/R = 1/R 1 +1/R 2. We can see this by noticing that the top path has current I 1 = (V 0 V 1)/R 1 and the bottom path has current I 2 = (V 0 V 1)/R 2, and the overall current I = I 1 + I 2 = (V 0 V 1)/R. It turns out that resistive networks and random walks have a lot in common. Here is one connection.
WebThe probability that a random walk will return to the origin before hitting Fn will then be given by 1 deg O X x˘O gn(x) (5) By Ohm’s law this is equal to 1 (deg O)(resistance between O and Fn) (6) So if the resistance between O and Fn is finite, the random walk is transient, but if it is infinite, the random walk is recurrent.
