In the field of advertising, there are always situations in which individuals or companies promote their products in order to find retrieval opportunities and attract customers in a competitive environment. Several goals are followed in this paper. First, the historical development of applications of differential games in modeling strategic situations in competitive advertising is mentioned. We then introduce the problem in a duopoly market under the influence of uncertainty in the framework of a stochastic differential game. Finding the equilibrium strategy for this problem requires solving a nonlinear partial differential equations system also known as the Hamilton-Jacoby equation. Another purpose of this paper is to propose an efficient and appropriate computational method for solving the Hamilton-Jacobi partial differential equations. The proposed method for solving the problem is a combination of collocation methods by the derivative operator matrix based on Chelyshkov polynomials and policy iteration method. The advantage of using the policy iteration method is that at each step, instead of finding the solution to a nonlinear partial differential equation, it is sufficient to solve a sequence of linear partial differential equations systems. The convergence of the proposed method is provided in detail. Finally, we solve the corresponding Hamilton-Jacobi equations system by the proposed iterative algorithm.
