Abstract
Some of the well-known convergence acceleration algorithms, when viewed as two-variable difference equations, are equivalent to discrete soliton equations. It is shown that the η-algorithm is nothing but the discrete KdV equation. In addition, one generalized version of the ϱ-algorithm is considered to be an integrable discretization of the cylindrical KdV equation.
