“…The pantograph differential equations have many applications in the area of theory [2], cell-growth biological based models [3] and control system [4]. The pantograph differential equations have been solved by many techniques, some of them are intelligent networks [5], Chebyshev spectral scheme [6], spectral tau scheme [7], multidimensional homotopy optimal asymptotic scheme [8], Genocchi operational based matrix scheme [9], least-squares-Epsilon-Ritz scheme [10], Taylor operation scheme [11], Galerkin multi-wavelets scheme [12], heuristic computing approach [13], Sinc numerical scheme [14], Laplace transform scheme [15], spectral collocation approach [16], multistep block method [17], Legendre Tau computational scheme [18] and Euler-Maruyama scheme [19]. This singular study is considered very significant due to its extensive applications in radiators cooling, dusty fluids, classical/quantum-based mechanics, models of gas cloud and galaxies [20][21][22].…”
