Abstract

Ergodic computational aspects of the Jacobi algorithm, a generalization to two dimensions of the continued fraction algorithm, are considered. By means of such computations the entropy of the algorithm is estimated to be 3.5. An approximation to the invariant measure of the transformation associated with the algorithm is obtained. The computations are tested by application to the continued fraction algorithm for which both entropy and the invariant measure are known.
