This article deals with the issue of convergence of the Adaptive Cross Algorithm (ACA) and argues that the stopping criterion used in this algorithm can lead to a premature stop, and yield inaccurate results as a consequence. A multiple restart, which is simple and effective, is proposed to improve the robustness. © 2009 Wiley Periodicals, Inc.
