Abstract
We describe a method to compute renormalized coupling constants in a M onte Carlo renormalization group calculation. It can be used, e.g., fo r lattice spin or gauge models. The basic idea is to simulate a joint system of block spins and canonical demons. Unlike the Microcanonical Renormalization Group of Creutz et al. it avoids systematical errors i n small volumes. We present numerical results for the O(3) nonlinear s igma-model.
