A [VMC](http://en.wikipedia.org/wiki/Variational_Monte_Carlo) implementation to find the ground state of the Simple Harmonic Oscillator.
// Compile with g++ -O2 -std=c++0x sho_test.cc -o sho_test
// or (gnu gcc 4.7 or above)
// Compile with g++ -O2 -std=c++11 sho_test.cc -o sho_test
// This package finds the ground state of the Simple Harmonic Oscillator
// with a test function \frac{\sqrt\alpha}{\pi^{\frac{1}{4}}} \exp( - \frac{1}{2} x^2\alpha^2)
