Probability distributions of bump widths for a Gaussian threshold distribution. Top: probability density of Δ values for a Gaussian threshold distribution. (White is high, black low.) The deterministic solution is superimposed in blue. Bottom: fraction of solutions which are stable. (\(\mathit {Black}=0\), \(\mathit{white}=1\).) Parameter values are \(\alpha=5\), \(B=0.76\), \(\beta=3\), \(\epsilon=0.002\), \(\kappa=0.5\) and \(\sigma^{2}=4\)
