title: Iterative renormalization group for anomalous dimension in a nonlinear diffusion process.
abstract: We construct a classical successive method, the Picard method in integral equation theory, to make an iterative algorithm with the renormalization group (RG) approach to calculate the anomalous dimension in a nonlinear diffusion equation. We find our result improves than the original RG work because we begin with the var epsilonth RG solution, not the trivial fixed-point solution.
