For each lattice site there is a discrete variable such that , representing the site's spin. A spin configuration, is an assignment of spin value to each lattice site. For any two adjacent sites there is an interaction . Also a site has an external magnetic field interacting with it. The energy of a configuration is given by the Hamiltonian function
