Multi-Objective Calibration For Agent-Based Models (2004)
Rogers, Alex, Von Tessin, Peter
Agent-based modelling is already proving to be an immensely useful tool for scientific and industrial modelling applications. Whilst the building of such models will always be something between an...

A mechanism for multiple goods and interdependent valuations (2004)
Rajdeep K Dash, Alex Rogers, Nicholas R Jennings
Abstract. This paper reports on the design of an auction mechanism for allocating multiple goods when the buyers have interdependent valuations. We cast the problem as a multi-agent system consisting...

Phase Transitions in Sexual Populations subject to Stabilising Selection (2003)
In this paper we show that a simple model of an evolving sexual population, which dates back to some of the earliest work in theoretical population genetics, exhibits an unexpected and previously...

The dynamics of a genetic algorithm on a model hard optimization problem (2000)
Alex Rogers, Adam Prugel-bennett
A model of a hard optimization problem suggested in the literature is considered. The dynamics of a genetic algorithm (GA) using ranking selection, mutation and uniform crossover are completely...
Modelling the dynamics of a steady state genetic algorithm (1999)
Alex Rogers, Adam Prugel-bennett
A comparison is made between the dynamics of steady state and generational genetic algorithms using the statistical mechanics approach developed by PrugelBennett, Shapiro and Rattray. It is shown...
Adam Prugel-bennett, Alex Rogers
This paper is an introduction to the mathematical modelling of the dynamics of genetic algorithms. The distinguishing feature of this approach is that we consider macroscopic properties of the...
