Figure 13From: Dynamics of bright and dark multi-soliton solutions for two higher-order Toda lattice equations for nonlinear wavesOne-soliton solution (52) with the parameters \(r_{1}=-1\), \(r_{2}=1\), \(\lambda_{1}=-1\), \(\lambda_{2}=-4\) when \(N=1\). (a) Exact solution; (b) Time evolution using exact solution (52) as an initial condition; (c) Time evolution using exact solution (52) perturbed by a 20% noise as the initial conditionBack to article page
