Abstract

We propose a stochastic generalization of the multigrid method, which reduces critical slowing down in Monte Carlo computations of lattice field theories. For free fields, critical slowing down is completely eliminated. For a 4 model, numerical experiments show a factor of 10 reduction, over a standard heat-bath algorithm, in the work needed to get a given accuracy (error-bar size).
