Evolution of replicase activity. Change of replicase activity (black) and replication rate (grey) for hard and soft trade-off. Fixed parameters: grid size: G = 300 × 300; system size: n = 4, of which one is a mutable parasite; k max = r max = 40; length of simulations: t max = 20.000; empty site claim: C e = 2.0; decay rate for all replicators: p d = 0.2; replication rates k1 = 2.0, k2 = 4.0, k3 = 6.0 and k4 = 8.0 (parasite). a: hard trade-off: h = 1, D = 4, σ r = 0.0, a = 1.0. b: soft trade-off: h = 1, D = 4, σ r = 0.1, a = 1.0. c: The same as b with faster replicator diffusion:h = 1, D = 20, σ r = 0.1, a = 1.0.
