Integrable algorithms are numerical algorithms that rely on basic ideas from the mathematical theory of

Generally, it is hard to accurately compute the solutions of nonlinear differential equations due to its non-linearity. In order to overcome this difficulty, R. Hirota has made discrete versions of integrable systems with the viewpoint of "Preserve mathematical structures of integrable systems in the discrete versions".[9]^{[10][11][12][13]}

At the same time, Mark J. Ablowitz and others have not only made discrete soliton equations with discrete Lax pair but also compared numerical results between integrable difference schemes and ordinary methods.^{[14][15][16][17][18]} As a result of their experiments, they have found that the accuracy can be improved with integrable difference schemes at some cases.^{[19][20][21][22]}
