Simulation

• The world is a simple two-dimensional rectangle with integer positions
• Agents can occupy the same space
• Agents can make one move per simulation step, either by trying to move by at most one unit in both directions or by trying to tag another actor
• Agents need to be at most one unit away in both directions from others in order to tag them
• Agents act at the same time and their actions are validated against the previous state
