An evolutionary agent-based model of pre-state warfare patterns: cross-cultural tests

An agent can observe its local environment and perform certain actions. The agent is oriented in space and has a field of vision. The field of vision consists of four cells: the cell the agent currently occupies, and the adjacent cells directly to the left, front, and right relative to the orientation of the agent. The agent lives in a discrete time. The agent executes one of seven actions during the one time step: to rest, to consume a resource, to turn to the left/right, to move forward to the next cell, to divide, or to fight.
