Query: The Factorization Method for Monte Carlo Simulations of Systems With a
  Complex Action   We propose a method for Monte Carlo simulations of systems with a complex
action. The method has the advantages of being in principle applicable to any
such system and provides a solution to the overlap problem. In some cases, like
in the IKKT matrix model, a finite size scaling extrapolation can provide
results for systems whose size would make it prohibitive to simulate directly.
