Summary:
Several methods for estimating initial values of moving intrinsic localized modes (moving ILMs) are numerically investigated in this report. Proper velocity and lifetime are evaluated for created moving ILMs in order to compare each method of the initial value estimation. As a result, the two methods, the spline interpolation method using numerically rigorous moving ILMs and the perturbation method using eigenvectors of standing ILM, show a good performance to estimate initial values of moving ILMs.
