Figure 7From: Fractional optimal control in transmission dynamics of West Nile virus model with state and control time delay: a numerical approachNumerical comparisons of the approximate solutions at \(\mathbf{d}=10\) and \(\mathbf{d}=0\) by using NSFDM. The approximate solutions of the fractional delay optimal control problem at \(\mathbf{d}=10\) and the fraction non-delay optimal control problem at \(\mathbf{d}=0\) when \(\alpha =0.98\), and \(\Delta t=0.1\)Back to article page
