Overview and History

Laws and institutions are constantly tending to gravitate. Like clocks, they must be occasionally cleansed, and wound up, and set to true time. 

The purpose of law is to prevent the strong always having their way. 

Among the various ways in which Monte Carlo methods can be utilized in solving the Schrodinger equation, there are four methods commonly termed quantum Monte Carlo methods. These are the variational quantum Monte 

Carlo method (VQMC), the diffusion quantum Monte Carlo method (DQMC), the Green s function quantum Monte Carlo method (GFQMC), and the path integral quantum Monte Carlo method (PIQMC). These methods are by their nature strongly related and each has its own peculiar advantages and disadvantages relative to the others. 

The variational method VQMC is fundamentally the same as the conventional analytic variational method except that the required integrals are evaluated using special Monte Carlo methods. The method has its roots in a numerical method reported by Frost ° in 1942. In Frost s own words  

As a part of this calculation, Frost estimated the expectation value of the energy (E) from the local energies = H j/o/Vo wavefunction To, using / as a weighting factor according to 

Conroy s VQMC calculations were shortly followed by those of McMil-lan for liquid helium. McMillan used the Metropolis algorithm to sample the configuration space for points with probabilities proportional to j/o. Only very recently has a much more efficient method for choosing points—anticipated to some extent by Conroy—been devised.
