Cycling in a stochastic learning algorithm for normal form games

Posch, Martin - In: Journal of Evolutionary Economics 7 (1997) 2, pp. 193-207

In this paper we study a stochastic learning model for 2, 2 normal form games that are played repeatedly. The main emphasis is put on the emergence of cycles. We assume that the players have neither information about the payoff matrix of their opponent nor about their own. At every round each...

Using co-evolutionary programming to simulate strategic behaviour in markets

Price, Tony Curzon - In: Journal of Evolutionary Economics 7 (1997) 3, pp. 219-254

This paper describes the use of a genetic algorithm (GA) to model several standard industrial organisation games: Bertrand and Cournot competition, a vertical chain of monopolies, and a simple model of an electricity pool. The intention is to demonstrate that the GA performs well as a modelling...

New Monte Carlo Algorithms for Classical Spin Systems

Barkema, G. T.; Newman, M. E. J. - Santa Fe Institute - 1997

We describe a number of recently developed cluster-flipping algorithms for the efficient stimulation of classical spin … models near their critical temperature. These include the algorithms of Wolff, Swendsen and Wang, and Niedermeyer, as well as … describe the application of these algorithms to Ising, Potts, and continuous spin models. …
