10. We construct a triangular lattice of 400 spins with half of the spins up on the left and half of the spins down on the right. We then minimize the energy of the system by allowing the spins to relax numerically with a quasi-Newton method. We find for zero external field, J=-2 and K=-1, an energy τ of 5.5 per lattice constant.
