If you have a question about this talk, please contact Gaurav.

As non-specialists in renormalization, we have tried to understand Sect VI of the famous 1975 Review of Modern Physics by K. G. Wilson that has remained cryptic to many. I will discuss a practical and un-biased Monte Carlo algorithm that we have implemented for the two-dimensional Ising model. Inspired by the original numerical method, it integrates modern twists in sampling, and that might be useful in other contexts (work with K. Sathwik).
