“…For such classes of problems, several authors have analyzed a broad range of statistical and numerical methods in approximate solutions. For more details, the readers can consult the works discussed in [25,41,33,55,35,26,38,48,34,43,37,4,29] and references therein. In this paper, we develop an efficient third-step second-order convergent explicit numerical approach for solving a system of nonlinear ODEs modeled by the dynamic of poverty and corruption.…”

“…The author [21] developed a twostep numerical scheme with convergence order O(τ 2− γ 2 + h 4 ) for solving the time-fractional convectiondiffusion-reaction equation with constant order derivative. For classical integer order ordinary/partial differential equations such as: Navier-Stokes equations, systems of ODEs, mixed Stokes-Darcy model, Shallow water problem, convection-diffusion-reaction equation, advection-diffusion model and conduction equation [18,5,20,24,39,26,29,37,28,27,14,32,23,50], a wide set of numerical techniques have been developed and deeply analyzed. For more details, we refer the readers to [30,38,19,45,33,34,44,22] and references therein.…”

“…Specifically, the hybrid version of MacCormack has been used to solve the mixed Stokes-Darcy and twodimensional time-dependent incompressible Navier-Stokes equations while the three-level time-split Mac-Cormack was applied to two-dimensional time-dependent reaction-diffusion, heat conduction, convectiondiffusion equations and linear/nonlinear convection-diffusion-reaction equations with constant coefficients (diffusive term equals 1 and convective velocity in the range: −1, 0.8 and 1). The analysis has suggested that the three-level explicit time-split MacCormack is fast, second order convergent in time and fourth order accurate in space [26,25,27,24,29,28,23,30,31,32]. We recall that the three-level time-split applies to a time dependent problem of the form: u t = A 1 (u) + A 2 (u), where A j (j = 1, 2) are differential operators, so that each subproblem u t = A j (u), j = 1, 2, is solved independently using the original MacCormack approach.…”
