Pursuit–Evasion Problems and Viscosity Solutions of Isaacs
In the continuous formulation of pursuit-evasion games, the environment is modeled geometrically, typically taking the form of the euclidean plane or another manifold. Variants of the game may impose maneuverability constraints on the players, such as a limited range of speed or acceleration.
This paper considers a spacecraft pursuit-evasion problem taking place in low earth orbit. The problem is formulated as a zero-sum differential game in which there are two players, a pursuing spacecraft that attempts to minimize a payoff, and an evading spacecraft that attempts to maximize the same payoff. We introduce two associated optimal control problems and show that a saddle point for the differential game exists if and only if the two optimal control problems have the same optimal value.
Finally, two representative pursuit-evasion differential games are studied in detail: the two-cutters and fugitive ship differential game and the active target defense differential game. These problems provide two important applications and, more importantly, they give great insight into the realization of cooperation between friendly agents in order to form a team and defeat the adversary.

By building a linear regression model from a large data set, produced by an indirect heuristic optimization algorithm, one can quickly map pursuer relative starting positions to terminal capture positions.
This kind of differential game is called a pursuit-evasion game because the optimal strategies aim at minimizing (the pursuer) or maximizing (the evader) the relative distance at the final time t f, called miss distance. One of the most important features of the pursuit-evasion games formulation is the definition of a structure for the game space with capture and avoidance regions where finite miss is guaranteed.

In game theory, differential games are a group of problems related to the modeling and analysis of conflict in the context of a dynamical system. More specifically, a state variable or variables evolve over time according to a differential equation. Early analyses reflected military interests, considering two actors—the pursuer and the evader—with diametrically opposed goals. More recent analyses have reflected engineering or economic considerations.

The evasion and the pursuit boundaries are investigated for the attacker when the three players use the one-to-one optimal guidance laws, which are derived based on differential game theory.
