restricted Boltzmann machine (RBM) wave function

This code calculates the ground state of 1d AF Heisenberg model using the RBM wave function.
This python code is ported from the following fortran code developed by Yusuke Nomura https://github.com/compsci-alliance/many-body-problems/blob/master/2018_ss/Summer_School_RBM_solver.zip .
Example using the steepest descent method:
Example using the stochastic reconfiguration method:
