Abstract
In a previous paper, we have described a method to perform Fixed-Node Quantum Monte Carlo calculations for lattice fermions. In this paper, we present an extension of this method, by which it is possible to find information on the properties of the exact ground-state wave function. We give some further illustrations of the FNMC and the extended methods.
