Fractional-Derivative Approximation of Relaxation in Complex Systems by Kin M. Li, Mihir Sen, Arturo Pacheco-Vega

“…The Caputo definition of the fractional derivative, and the Mittag-Leffler function, is used to obtain the corresponding solutions. Since the set of parameters for the model and its initial conditions are nonunique, and there are small but significant differences in the predictions from the possible models thus obtained, the SI operation is carried out via global regression of an error-cost function by a simulated annealing optimization algorithm. …”
