Figure 6From: Fractional optimal control in transmission dynamics of West Nile virus model with state and control time delay: a numerical approachThe approximate solutions of the fractional delay optimal control problem by using NSFDM. When \(0 \leq u_{1}\leq 0.8\), \(0 \leq u_{2}\leq 0.5\), with \(\mathbf{d}=5\) and different α, and \(\Delta t=0.1\)Back to article page
