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…
Robust criticality of Ising model on rewired directed networks
Adam Lipowski, Krzysztof Gontarek, Dorota Lipowska
We show that preferential rewiring, which is supposed to mimick the behaviour of financial agents, changes a directed-network Ising ferromagnet with a single critical point into a…
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…
