Insensitivity of patch-finding performance to worst patch statistics. (a) ${\overline{T}}_{\mathrm{arrive}}$ increases with λ₃, as does θ^opt, since the worst patches become less easy to distinguish from the best (λ₁ = 3). Here λ₂ = 2, τ = 5, p₁ = p₂ = p₃ = 1/3. (b) ${\overline{T}}_{\mathrm{arrive}}^{\mathrm{opt}}$ increases with p₂ (while p₁ = 0.333 and p₃ = 1 − p₁ − p₂), as does θ^opt. All curves for ${\overline{T}}_{\mathrm{arrive}}$ computed from 10⁶ Monte Carlo simulations.
