The Ghost in the Model (and Other Effects of Floating Point Arithmetic)

Polhill, J. Gary; Izquierdo, Luis R.; Gotts, Nicholas M. - In: Journal of Artificial Societies and Social Simulation 8 (2004) 1, pp. 5-5

This paper will explore the effects of errors in floating point arithmetic in two published agent-based models: the first a model of land use change (Polhill et al. 2001; Gotts et al. 2003), the second a model of the stock market (LeBaron et al. 1999). The first example demonstrates how branching...

Comparison of four software packages applied to a scattering problem1Professor Ralph E. Kleinman, University of Delaware, USA, in memoriam.1

Albertsen, Niels Christian; Chesneaux, Jean-Marie; … - In: Mathematics and Computers in Simulation (MATCOM) 48 (1999) 3, pp. 307-317

We investigate characteristic features of four different software packages by applying them to the numerical solution of a non-trivial physical problem in computer simulation, viz., scattering of waves from a sinusoidal boundary. The numerical method used is based on boundary collocation. This...
