✦ Synopsis
a b s t r a c t
This study addresses the optimization of rational fraction approximations for the discretetime calculation of fractional derivatives. The article starts by analyzing the standard techniques based on Taylor series and Padé expansions. In a second phase the paper re-evaluates the problem in an optimization perspective by tacking advantage of the flexibility of the genetic algorithms.
