A discrete-time Lagrangian network for solving constrained quadratic programs.

A discrete-time recurrent neural network which is called the discrete-time Lagrangian network is proposed in this letter for solving convex quadratic programs. It is developed based on the classical Lagrange optimization method and solves quadratic programs without using any penalty parameter. The condition for the neural network to globally converge to the optimal solution of the quadratic program is given. Simulation results are presented to illustrate its performance.

Urbanisation in China: a review of its causal mechanisms and spatial relations.

This article reviews "the forces underpinning Chinese urbanization.... This paper is divided into two main parts. The first addresses the (non-spatial) causal mechanisms between 1949 and 1977. Neither the ideological, the class, nor the economic formulation has touched on the more systemic mechanisms related to the socialist state and the shortage economy. This paper attempts to redress the imbalance by examining the advantages of combining Kornai's shortage model with Foucault's concept of governmentality. By drawing on concepts of spatial contingency, spatial boundary and locality effects, the second part of the paper argues that spatial relations do play significant roles in revealing Chinese urbanisation policies and patterns."
