摘要：

A review of new developments in numerical stochastic perturbation theory (NSPT) is presented, In particular, the status of the extension of the method to gauge fixed lattice QCD is reviewed and a first application to compact (scalar) QED is presented. Lacking still a general proof of the convergence of the underlying stochastic precesses, a self-consistent method for testing the results is discussed.
