Generating Chaotic Trajectories for Patrolling Agents
Cover Story: This study considers the problem of constructing chaotic maps where the statistical mean value can be appropriately controlled by tuning the map's parameters. Such maps can be used in chaos-based applications. To showcase this, these maps are used as sources of randomness in generating unpredictable trajectories for UAVs surveilling an area. The trajectory inherits the randomness of the chaotic map used as a seed, which results in chaotic motion patterns. View this paper
