A fresh look on economic evolution from kinetic viewpoint

Lehmann-Waffenschmidt, Marco - Fakultät Wirtschaftswissenschaften, Technische … - 2003

The present paper makes a contribution to fill in a gap left open by dynamic theory and evolutionary economics as well. While the "closed loop" dynamic theory has explanation power in analyzing evolving economic systems at the price of neglecting the possible occurrence of non anticipated...

Multistage extremal optimization for hard travelling salesman problem

Zeng, Guo-Qiang; Lu, Yong-Zai; Mao, Wei-Jie - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 21, pp. 5037-5044

The adjustable parameters of probability distributions adopted by extremal optimization (EO) and its modified versions play a critical role in controlling their performances. Unlike the traditional static probability distribution based strategy, this paper presents a novel method called...

Topology, Metric and Dynamics of Social Systems

Klüver, Jürgen; Schmidt, Jörn - In: Journal of Artificial Societies and Social Simulation 2 (1999) 3, pp. 7-7

similar cellular automata are governed by control parameters. Less well known is the fact that the geometry of these … artificial systems, understood as their topology and metric, also contain specific control parameters. These "geometrical …" control parameters can be expressed using graph theoretical concepts such as the density of graphs or geodetical properties …

A fresh look on economic evolution from the kinetic viewpoint

Lehmann-Waffenschmidt, Marco - In: Journal of Evolutionary Economics 15 (2005) 5, pp. 481-503

Dynamic economic theory and evolutionary economics are both subject to the trade-off between explanation power and accounting for novelty. The present paper makes a contribution to filling in this gap basing on a general equilibrium model including production and taxes. Our notion of an "open...

Determination of a control function in three-dimensional parabolic equations

Dehghan, Mehdi - In: Mathematics and Computers in Simulation (MATCOM) 61 (2003) 2, pp. 89-100

This study presents numerical schemes for solving two three-dimensional parabolic inverse problems. These schemes are developed for indentifying the parameter p(t) which satisfy ut=uxx+uyy+uzz+p(t)u+φ, in R×(0,T], u(x,y,z,0)=f(x,y,z),(x,y,z)∈R=[0,1]3. It is assumed that u is known on the...
