FIG. 4. — (a) The final walker positions for a representative N = 2 simulation are shown as points. This is overlayed on a probability distribution heat map, calculated using P^t(x, y) = P^t(x)P^t(y). (b) Probability distributions for the distance to the origin, averaged over all simulations, all walkers and for 10 cycles spaced evenly between cycle 1000 and cycle 10 000. Distributions are shown separately for N = 2, 5, 10, and 20. (c) The expectation values of these curves as a function of N.
