摘要：

We develop a simple mesh-smoothing algorithm for adaptively improving finite-element triangulations. The algorithm makes use of a posteriori error estimates which are now widely used in finite-element calculations. In this paper we derive the method, present some numerical illustrations, and give a brief analysis of the issue of uniqueness.
