Truels, or the survival of the weakest
Pau Amengual, Raúl Toral
In this paper we review some of the main results obtained in the field of truels. A "truel" is a generalization of a duel involving three players. Depending on the rules used for c…
Reversals of chance in paradoxical games
P. Amengual, P. Meurs, B. Cleuren +1
We present two collective games with new paradoxical features when they are combined. Besides reproducing the so--called Parrondo effect, where a winning game is obtained from the…
Distribution of winners in truel games
R. Toral, P. Amengual
In this work we present a detailed analysis using the Markov chain theory of some versions of the truel game in which three players try to eliminate each other in a series of one-t…
Efficiency of discrete-time ratchets
P. Amengual, R. Toral, A. Allison +1
Recently there has been much interest in discrete forms of Brownian ratchets, using a game-theoretic formalism. Using the approach pioneered by Parrondo, we develop a new method fo…
Neighborhood models of minority opinion spreading
C. J. Tessone, R. Toral, P. Amengual +2
We study the effect of finite size population in Galam's model [Eur. Phys. J. B 25 (2002) 403] of minority opinion spreading and introduce neighborhood models that account for loca…
Parrondo's games and the zipping algorithm
Pau Amengual, Raul Toral
We study the relation between the discrete--time version of the flashing ratchet known as Parrondo's games and a compression technique used very recently with thermal ratchets for…
