Table 1 Computation of \(L_{1}\) and \(L_{\infty }\) errors using MMPDE and MMDAE methods with \(\rho =10^{4}, \alpha =1.5, \beta =0.1, a=1.015, \tau =10^{-7}, N=50\), at time \(t=2.5\times 10^{-3}\)

From: On the numerical solution of Fisher’s equation with coefficient of diffusion term much smaller than coefficient of reaction term
