Bump solutions as a function of κ 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 \(\alpha=5\), \(B=0.76\), \(\beta=3\), \(h_{0}=0.05\), \(\epsilon=0.01\) and \(\sigma^{2}=1/\kappa\)
