Abstract
The Adaptive Cross Approximation (ACA) algorithm is a well-established tool in numerical modelling, used for fast and accurate compression of interaction matrices. The tradeoff between efficiency and memory requirements on the one hand, and accuracy on the other, is governed by a precision threshold and an accompanying approximate convergence criterion. It has long been known that this convergence criterion is sometimes very unreliable, yet despite the widespread success of the ACA, no viable al...
