Figure 1From: Self-adaptive moving mesh schemes for short pulse type equations and their Lax pairsThe numerical simulation of the 2-loop soliton solution of the SP equation. The poits shows the numerical values, and the continuous curve shows the exact value, and the points on the bottom of graphs show the distribution of mesh grid points. p1=0.9, p2=0.5, a1=e−2, a2=e−8.Back to article page
