heal.abstract	Monte Carlo simulations of a system whose action has an imaginary part areconsidered to be extremely difficult. We propose a new approach to this`complex-action problem', which utilizes a factorization property ofdistribution functions. The basic idea is quite general, and it removes theso-called overlap problem completely. Here we apply the method to anonperturbative study of superstring	en
