Minority games with finite score memory
Damien Challet, Andrea De Martino, Matteo Marsili +1
We analyze grand-canonical minority games with infinite and finite score memory and different updating timescales (from `on-line' games to `batch' games) in detail with various com…
Replica symmetry breaking in the minority game
Andrea De Martino, Matteo Marsili
We extend and complete recent work concerning the analytic solution of the minority game. Nash equilibria (NE) of the game have been found to be related to the ground states of a d…
Percolation and lack of self-averaging in a frustrated evolutionary model
Andrea De Martino, Andrea Giansanti
We present a stochastic evolutionary model obtained through a perturbation of Kauffman's maximally rugged model, which is recovered as a special case. Our main results are: (i) exi…
Critical percolation and lack of self-averaging in disordered models
Andrea De Martino, Andrea Giansanti
Lack of self-averaging originates in many disordered models from a fragmentation of the phase space where the sizes of the fragments remain sample-dependent in the thermodynamic li…
The geometrically broken object
Andrea De Martino
We introduce an analytically solvable model for a fragmented object that, despite of a low degree of randomness and of the extreme simplicity of the breaking process, displays non…
