Multi-dimensional transitional dynamics: A simple numerical procedure

Trimborn, Timo; Koch, Karl-Josef; Steger, Thomas M. - 2004

We propose the relaxation algorithm as a simple and powerful method for simulating the transition process in growth models. This method has a number of important advantages: (1) It can easily deal with a wide range of dynamic systems including multi-dimensional systems with stable eigenvalues...

Computing Center Manifolds: A Macroeconomic Example

Haro, Alex; Gomis-Poruqeras, Pere - Society for Computational Economics - SCE - 2004

When crossing the boundary of stability of a given dynamical system only indicates a bifurcation point and the type of the bifurcating solutions. But it doesn't tell us how and how many new solutions bifurcate or disappear in a bifurcation point. To answer this question one has to take into...

Fast computation of equispaced Pareto manifolds and Pareto fronts for multiobjective optimization problems

Pereyra, Victor - In: Mathematics and Computers in Simulation (MATCOM) 79 (2009) 6, pp. 1935-1947

In this paper, we consider the problem of generating a well sampled discrete representation of the Pareto manifold or the Pareto front corresponding to the equilibrium points of a multi-objective optimization problem. We show how the introduction of simple additional constraints into a...
