“…As the KdV equation possesses positive solitons only, they never produce large waves in the focal point (as shown in Figure 1), according to (46). This conclusion is in qualitative agreement with the results of direct numerical simulations of irregular soliton ensembles, 26,30 which did not observe extreme wave events in the ensembles of unipolar solitons.…”

“…. Such "absorb-emit" collisions were also considered in Ref 26. as the reason for the generation of abnormally high waves in a soliton gas.The presented scenarios of soliton collisions are similar to the ones depicted in Ref 17.…”

“…Hence, the peculiarity of the 'absorb-emit' collision of bipolar solitons yields occurrence of higher waves than could happen in the situation of a unipolar soliton gas. In particular, the occurrence of high waves which are twice higher than the typical soliton height was observed in numerical simulations [6].…”

“…If two eigenvalues λ n and λ m turn out to be close to each other, the numerical implementation of both the dressing method and the determinant formula may fail due to very small denominators in Eqs. (12), (14) (for λ n = λ m these equations become indeterminate). To avoid such situations, we use threshold δλ = 10 −9 for minimal distance between the eigenvalues |λ n − λ m | > δλ, n, m = 1, ..., N, m = n.…”
