Emergence of collective escaping strategies of empathie caribou agents with swarming behavior implemented in wolf-caribou predator-prey problem

摘要

We investigate whether socio-psychological aspects - such as empathy and grouping (swarming) - implemented in caribou agents improves the efficiency of the simulated evolution (via genetic programming) of their escaping behavior or the effectiveness of such a behavior in the wolf-caribou predator prey pursuit problem (WCP). The latter comprises a team of inferior caribou agents attempting to escape from a single yet superior (in terms of sensory abilities, raw speed, and maximum energy) wolf agent in a simulated two-dimensional infinite toroidal world. We experimentally verified the survival value of empathy in that it improves both the efficiency of evolution of the escaping behavior and the effectiveness of such a behavior. Also, we concluded that swarming facilitates a faster evolution of caribou agents while preserving the effectiveness of their evolved behavior.
