To solve this problem numerically, an appropriate difference scheme is constructed by using the method of integral identities which contains basis functions and interpolating quadrature rules with weight and remainder term in integral form. Besides, the method is proved to be first-order convergent in discrete maximum norm. The numerical illustration provided support the theoretical results. Finally, the proposed method is compared with the imeninfo:eu-repo/semantics/openAccessPlicit Euler MethodDelay Differential EquationInitial Value ProblemFinite Difference MethodError EsTimateConvergenceArticle222Q2Q3625638WOS:000741090800010
