Abstract For a conflict-controlled dynamical system described by neutral-type functional differential equations in Hale’s form, a differential game is considered in the classes of control strategies with a guide for a minimax-maximin of the quality index, which evaluates the system’s motion history implemented by the terminal time moment. The differential game is associated with the Cauchy problem for a functional Hamilton–Jacobi type equation in coinvariant derivatives. It has been proven that the game value functional coincides with the minimax solution of this problem. A method of constructing the optimal strategies of players is given. The approximation by ordinary Hamilton–Jacobi equations in partial derivatives is proposed for this functional Hamilton–Jacobi equation in coinvariant derivatives.
Keywords differential game, neutral-type equations, coinvariant derivatives, Hamilton–Jacobi equation, minimax solution, control with a guide, optimal strategies
