Monte Carlo calculation of renormalized coupling parameters. II. d=3 Ising model

The majority-rule, block-spin, renormalization-group transformation for the d=3 Ising model is studied, with the use of a recently developed technique for calculating renormalized coupling parameters from a single Monte Carlo simulation. Renormalization-group trajectories and the approximate fixed point are calculated. Improvements in the convergence of the Monte Carlo renormalization-group calculations of critical exponents are discussed. © 1984 The American Physical Society.
