Publications

In a previous life in academia I did AI research, focused on evolutionary computation, multi-agent simulation and artificial life: genetic programming, the evolution of cooperation, swarms of flying agents, and the breve simulation environment that most of it ran on. Here’s the work I published, mostly with Lee Spector.
