If half of the agents are tracked, do we still report the last position of the non-tracked agents? If true, then we would just have a smaller tracking matrix–(100000, 2000, 3) for half. The last position file would still have 200,000 elements.
We want the final positions (alive and dead) of all agents regardless of what percentage are tracked. For this challenge, there should be a submission with 200,000 agents, even if only 50% are tracked. What we mean by tracking is that we have a record of where each agent moved since its birth. The path an agent takes can tell us a lot about the environment it is moving through and provides a gut check on how well the simulation performs.
