SUMMARY:Thermodynamic Integration\, fermion sign problem\, and real-space 
 renormalization - Werner Krauth\, ENS Paris\, Oxford

DESCRIPTION:As non-specialists in renormalization\, we have tried to under
 stand 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-biase
 d Monte Carlo algorithm that we have implemented for the two-dimensional I
 sing model. Inspired by the original numerical method\, it integrates mode
 rn twists in sampling\, and that might be useful in other contexts (work w
 ith K. Sathwik).\n\n*disclaimer!
