Navigating the N-Person Prisoner's Dilemma

Chris Tcaci and Chris Huyck wrote a paper for AI-2025: The Forty-fifth SGAI International Conference in Cambridge in December 2025.

abstract The research community has a great deal of knowledge about neural function and brain topology. This knowledge is by no means complete, but much of it is quite solid and is generally accepted as true. We try to take advantage of this knowledge as the basis of our models. For example, it is known that the brain is made up of neurons and these neurons connect to other neurons at places called synapses. (They may connect at other places, but most connections are synaptic.) When a pre-synaptic neuron fires, it sends activation (or inhibition) across the synapse, to the post-synaptic neuron. If the post-synaptic neuron collects enough energy it will fire.
