Fractional optimal control in transmission dynamics of West Nile virus model with state and control time delay: a numerical approach

open access: yesAdvances in Difference Equations, 2019
In this paper, an optimal control for a novel fractional West Nile virus model with time delay is presented. The proposed model is governed by a system of fractional delay differential equations, where the fractional derivative is defined in the Grünwald–
