Spatial evolution of the US urban system

Ioannides, Yannis; Overman, Henry G. - London School of Economics (LSE) - 2004

We examine spatial features of the evolution of the US urban system usingUS Census data for 1900 – 1990 with non-parametric kernel estimation techniques that accommodate the complexity of the urban system. We consider spatial features of the location of cities and city outcomes in terms of...

Spatial evolution character of multi-objective evolutionary algorithm based on self-organized criticality theory

Li, Jun-fang; Zhang, Bu-han; Liu, Yi-fang; Wang, Kui; … - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 22, pp. 5490-5499

This paper analyzes the spatial evolution character of multi-objective evolutionary algorithms using self …-organized criticality theory. The spatial evolution character is modeled by the statistical property of crowding distance, which displays a … speed of the state transition reflects the efficiency of the algorithm. We simulate the spatial evolution characters of …

Spatial Evolution of the US Urban System

Ioannides, Y; Overman, Henry - Centre for Economic Performance, LSE - 2000

We test implications of economic geography models for location, size and growth of cities with US Census data for 1900 û 1990. Our tests involve non-parametric estimations of stochastic kernels for the distributions of city sizes and growth rates, conditional on various measures of market...
