In the proposed framework of the EPA scheme\, the crowding effect-driven system is transfo rmed to an equivalent nonlinear global optimization problem by assimilatin g Padeě rational functions. The initial conditions\, boundedness\, and pos itivity of the solution are dealt with as problem constraints. Keeping in view the complexity of formulated optimization problem\, a hybrid of diffe rential evolution (DE) and a convergent variant of the Nelder-Mead Simplex algorithm is also proposed to obtain a reliable\, optimal solution. The c omparison of the EPA scheme results reveals that optimization results of a ll formulated optimization problems for the Covid-19 model with crowding e ffect are better than those of several modern metaheuristics. EPA-based so lutions of the Covid-19 model with crowding effect are in good agreement w ith those of a well-practiced nonstandard finite difference (NSFD) scheme. The proposed EPA scheme is less sensitive to step lengths and converges t o true equilibrium points unconditionally.\n DTSTART:20220127T160000Z DTEND:20220127T170000Z LOCATION:CA\, ZOOM SUMMARY:Evolutionary optimized Padeě approximation scheme for analysis of C ovid-19 model with crowding effect URL:/cim/channels/event/evolutionary-optimized-padee-a pproximation-scheme-analysis-covid-19-model-crowding-effect-337076 END:VEVENT END:VCALENDAR
