## Abstract Although it would be tempting to associate the Lewis structures to the maxima of the squared wave function |Ξ¨|^2^, we prefer in this paper the use of domains of the threeβdimensional space, which maximize the probability of containing oppositeβspin electron pairs. We find for simple sys

The problem of antisymmetry in the quantum Monte Carlo method is handled by a technique able to build up mobile nodal surfaces, self-adapting to the signed psip distribution. We define a function A as a sum of Gaussians, each one centered on a psip and with its own sign. This sum is extended to the
## Abstract Quantum Monte Carlo (QMC) calculations require the generation of random electronic configurations with respect to a desired probability density, usually the square of the magnitude of the wavefunction. In most cases, the Metropolis algorithm is used to generate a sequence of configurati
