Recent models for discrete Euclidean quantum gravity incorporate a sum over simplicial triangulations. We describe an algorithm for simulating such models in arbitrary dimension. As illustration we show results from simulations in four dimensions.
Attempts are made to construct exact invariants for a variety of time-dependent classical dynamical systems in three dimensions. We make use of the dynamical algebraic method for this purpose and explore several new systems admitting the invariants. In particular, systems involving both momentum and
