In this paper, a novel numerical method for solving the optimal control
problems (OCPs) are presented. This method uses Genocchi polynomials.
Some properties of Genocchi polynomials are given and the operational
matrix of derivative is constructed. This matrix helps us to convert the
nonlinear constrained optimal control problem to the nonlinear
programming one that can be solved by Maple programming software. The
presented method is applied on some numerical examples in order to show
