摘要：

To assess the validity of the Belinskii, Khalatnikov, and Lifshitz (BKL) approximation to mixmaster dynamics, it would be useful to evaluate the BKL discrete parameters as a by-product of the numerical solution of Einstein's equations. An algorithm to do this and results for a typical trajectory are presented.
