Abstract
First attempts in the application of Numerical Stochastic Perturbation Theo ry (NSPT) to the problem of pushing one loop further the computation of SU( 3) (SU(2)) pertubative beta function (in different schemes) are reviewed an d the relevance of such a computation is discussed. Other issues include th e proposal of a different strategy for gauge-fixed NSPT computations in lat tice QCD.
