Fig. 13.6 In blue: relative frequency distribution of the number of walkers in a house after 50
time-steps, obtained by running CoolWorld 100 times (Battery A), with initial conditions set by
clicking on ‘Special conditions’. In grey: exact probability distribution (calculated using Markov
chain analysis)
