Bump solutions as a function of ϵ for a Gaussian threshold distribution. Top: average number of total solutions (blue) and stable solutions (green) of (32)–(33) for a Gaussian threshold distribution. Bottom: fraction of solutions which are stable. Parameter values are \(\alpha=5\), \(B=0.76\), \(\beta=3\), \(h_{0}=0.05\), \(\kappa=0.1\) and \(\sigma^{2}=10\)
