Replicator-Mutator Equation — Quasispecies
Selection + mutation: error threshold, quasispecies, fitness landscapes
Parameters
Mutation rate μ:
0.02
Fitness peak height σ_f:
3.0
Landscape type:
Single peak
Multi-peak

Reset
Theory
dxᵢ/dt = Σⱼ fⱼ Qⱼᵢ xⱼ - φ xᵢ
Qⱼᵢ = μ^d(i,j)(1-μ)^(L-d(i,j))
Error threshold: μ_c ≈ ln(f_max)/L
Quasispecies = mutation-selection balance
