Variable step-size affine projection sign algorithm
Electronics Letters, 2012 Proposed is a variable step-size affine projection sign algorithm (APSA) based on the minimisation of mean-square deviation. Because the proposed algorithm calculates the optimum step size in every iteration, it ensures an improved performance in terms of convergence rate and misalignment, compared to conventional APSAs.

Invariant curves for variable step size integrators [PDF]
BIT, 1991 The behaviour of the numerical integration of the ordinary differential equation (1) \(\dot x=f(x)\), \(x\in \Omega \subset {\mathbb{R}}^ n\), (with a hyperbolic periodic solution) applying a one-step method with variable step size is investigated. It is shown that there exists an attractive (hyperbolic) invariant closed curve for the numerical method ...
