Phase transitions in Ising models on directed networks
Adam Lipowski, Antonio Luis Ferreira, Dorota Lipowska +1
We examine Ising models with heat-bath dynamics on directed networks. Our simulations show that Ising models on directed triangular and simple cubic lattices undergo a phase transi…

Statistical-mechanics approach to a reinforcement learning model with memory
Adam Lipowski, Krzysztof Gontarek, Marcel Ausloos
We introduce a two-player model of reinforcement learning with memory. Past actions of an iterated game are stored in a memory and used to determine player's next action. To examin…
