Time averaged cell concentrations in simulations with mutations between producers of many different production rates.

Three sets of initial conditions are described in the text. These converge to similar distributions in the long-time limit. Simulations were run for 100,000 time units and an average was taken over the second half of the simulation. Parameters: b = 10, c = 0.001, δt = 0.01, u = 0.0001, lattice: L = 1024x1024. The equilibrium concentration of S in these runs is close to 0.32.
