I am trying to write a predator-prey simulator and I have hit the wall with functional design. I would appreciate any help or pointers to relevant literature.

The simulator is that of a world populated with fish and sharks. It is a discrete-time multi-agent simulation and what I am struggling to think about is how to implement the illusion of parallelism in simulation. Since the problem is not specifically with OCaml (but the simulator is in OCaml), I have kept this email short and put all the details and the code on GitHub:

"On the subject of Toroidal Planets, Sharks and Fish."

It's only a hobby project, but it is of some interest to me, so I would really appreciate any advice.

Best regards,

Ollie
