Recently it has been shown that a physical hysteresis model has a unique mathematical solution for a given magnetic material. This solution gives maximum agreement between measured and simulated virgin curve and major loop. As the analytical solution is complicated and difficult to find it was necessary to find the optimum by an approximation. Standard optimization methods found only local optima, because the system is non-linear and non-convex. This paper shows how a stochastic method can be applied to fast approach the global solution.
