+As a final challenge, lets consider a spin glass system. 
+A simple yet illustrative model for a spin glass system is given by the Edwards-Anderson model, where a nearest neighbour Hamiltonian on a cubic 
+lattice, but with random exchange interactions are used. 
+
+The UppASD code can model Edwards-Anderson spin glasses by the keywords ``ea_model T`` and ``ea_sigma XX`` where ``ea_sigma`` contols
+the width of the Gaussian distribution of the randomized exchange interactions. Disregarding the ``ea_sigma`` keyword for now, 
+we can define a simple cubic system with randomized exchange with the following ``inpsd.dat``
+
+.. literalinclude:: EdwardsAnderson/inpsd.dat
+
+While the ``posfile`` and ``momfile`` are made as easy as possible
+
+.. literalinclude:: EdwardsAnderson/posfile
+.. literalinclude:: EdwardsAnderson/momfile
+
+Even though the exchange interactions will be randomized, we still have to set up a Hamiltonian with existing couplings since only 
+the magnitude and not the directions will be randomized. Thus we use the following ``jfile``
+
+.. literalinclude:: EdwardsAnderson/jfile
+
+With the glassy system setup. we end this exercise session with a friendly competition:
+
+ * Without changing the system size and Hamiltonian, apply your thermalization and minimization skills to get the lowest possible energy for this system.
+
+The participant with the lowest energy will get a symbolic price during the conference dinner.
