Pursuit and Evasion with Temporal Non-locality and Stochasticity
TLDR
The model has been extended to investigate the effects of stochasticity in chasing and escaping movements, reaction delays (temporal non-locality) when chasing, and the conversion of caught escapees to new chasers.
Chases and Escapes: From Singles to Groups
TLDR
This chapter presents the basic model and its rather complex behavior of a group of particles chasing another group, called “group chase and escape,” and introduces two order parameters to characterize the chasing and escaping in group.
Group chase and escape in the presence of obstacles
Dynamic properties of chasers in a moving queue based on a delayed chasing model
A delayed chasing model is proposed to simulate the chase behavior in the queue, where each member regards the closest one ahead as the target, and the leader is attracted to a target point with
Group chase and escape with prey's anti-attack behavior
Analysis of group chase and escape by honeycomb grid cellular automata
TLDR
By using numerical simulations of a cellular automaton with honeycomb grid, this paper discusses a method of group chase and escape by comparing several methods with the randomness of behaviour of the chasers and discusses the effectiveness of the Randomness.
Survival probability of a lazy prey on lattices and complex networks
TLDR
The proposed framework enables one to study the survival probability of such a prey being hunted by multiple predators on any given structure by predicting that, for the considered lattices, P sur reduces as the degree of the nodes of the lattice is increased, but for networks, the effect of the long-range connections in networks on P sur decreases.

Group Chase and Escape
We describe here a new concept of one group chasing another, called 'group chase and escape', by presenting a simple model. We will show that even a simple model can demonstrate rather rich and
Survival of an evasive prey
TLDR
A simple asymptotic relation lnP ev(t) ∼ (N/V)2lnP imm( t) between the survival probabilities of an evasive and an immobile prey is established and it is argued that a short-sighting prey undergoes an effective superdiffusive motion, as a result of its encounters with the predators, whereas a far-sighted prey performs a diffusive-type motion.
Collective motion due to individual escape and pursuit response.
TLDR
A simple model of Brownian particles interacting by biologically motivated pursuit and escape interactions is introduced and a strong dependence of experimentally accessible macroscopic observables on the relative strength of escape and pursuit is demonstrated and the scaling of the migration speed is determined with model parameters.
Chemotactic predator-prey dynamics.
TLDR
A discrete chemotactic predator-prey model is proposed in which the prey secrets a diffusing chemical which is sensed by the predator and vice versa and it is shown that steady hunting is unstable.
Kinetics of a diffusive capture process: lamb besieged by a pride of lions
The survival probability, , of a diffusing prey (`lamb') in the proximity of N diffusing predators (a `pride of lions') in one dimension is investigated. When the lions are all to one side of the

Probabilistic pursuit-evasion games: theory, implementation, and experimental evaluation
TLDR
A distributed hierarchical hybrid system architecture which emphasizes the autonomy of each agent, yet allows for coordinated team efforts is proposed, and components such as high-level pursuit policy computation, map building and interagent communication, and low-level navigation, sensing, and control are described.
Dynamic Noncooperative Game Theory
Traffic and related self-driven many-particle systems
TLDR
This article considers the empirical data and then reviews the main approaches to modeling pedestrian and vehicle traffic, including microscopic (particle-based), mesoscopic (gas-kinetic), and macroscopic (fluid-dynamic) models.
