Lagrange computational approach for fractional-order delay systems of Volterra integral and integro-differential equations

Abstract

In this paper, numerical solution depending on Lagrange cardinal operational collocation optimization method (LCOCOM) is introduced. The LCOCOM is developed to obtain the solutions of Volterra delay integral and integro-differential equations, as well fractional-order delay systems of Volterra integral and integrodifferential equations. We present numerical results and comparisons of existing treatments to demonstrate the efficiency and applicability of the proposed method. The proposed method gives more accurate solution with minimum number of approximation nodes in linear as well as nonlinear cases.
