Suboptimal universal strategies in an optimum-time game problem. (English. Russian original) Zbl 0885.90132

J. Appl. Math. Mech. 59, No. 5, 677-683 (1995); translation from Prikl. Mat. Mekh. 59, No. 5, 707-713 (1995).
Summary: A differential game in which the payoff functional is the time required for the phase point to reach the target set is considered. A construction of \(\varepsilon\)-optimal strategies, similar to the standard construction when the value function is everywhere differentiable, is proposed. The difference is that the gradient of a non-smooth and discontinuous value function is replaced by a certain quasigradient.
