These positive results encourage further development of analysis tools based on the techniques discussed. The results indicate that the latter two models reflect said energy differences correctly. Simulated games between different Go playing systems were used to test whether the models are able to capture the energy changes produced by moves between players of different skills. The third or Molecular-Go model, incorporates Common Fate Graphs, which are an alternative representation of the Go board that offers advantages in pattern analysis. The second or Generative Atomic-Go model, employs a Deep Belief Network (a generative graphical model popular in machine learning) to generate board configurations and compensate for the lack of information in mostly-empty boards.
The first or Atomic-Go model, consists of the straightforward measurement of local energy employing the adapted Ising Hamiltonian. The proposed models are increasingly complex. The Ising Hamiltonian is adapted to measure the 'energy' of the Go boards generated by the interaction of the game pieces (stones) as players make their moves in an attempt to control the board or to capture rival stones. Three different models of the game of Go are developed by establishing an analogy between this game and physical systems susceptible to analysis under the well-known Ising model in two dimensions.
