Figure 9From: Dynamics of bright and dark multi-soliton solutions for two higher-order Toda lattice equations for nonlinear wavesExact one-soliton solutions \(\widetilde{u}_{n}\) and \(\widetilde {v}_{n}\) in (50) with \(N=1\) via the parameters \(r_{1}=-1\), \(r_{2}=1\), \(\lambda_{1}=-1\), \(\lambda_{2}=-2\). (a) Exact solution; (b) Time evolution using exact solution as an initial condition; (c) Time evolution using exact solution perturbed by a 2% noise as the initial conditionBack to article page
