A line search filter inexact SQP method for nonlinear equality constrained optimization

This paper proposes an inexact SQP method in association with line search filter technique for solving nonlinear equality constrained optimization.For large-scale applications,it is expensive to get an exact search direction,and hence the authors use an inexact method that finds an approximate solution satisfying some appropriate conditions.The global convergence of the proposed algorithm is established by using line search filter technique.The second-order correction step is used to overcome the Maratos effect,while the line search filter inexact SQP method has q-superlinear local convergence rate.Finally,the results of numerical experiments indicate that the proposed method is efficient for the given test problems.     

重整热力学理论的方案

"热寂说"是热力学第二定律的宇宙学推论,由于涉及到宇宙未来、人类命运等重大问题,引起了科学界和哲学界一百多年持续不断的争论。本文从重力场影响介质温度分布出发,研究系统处于外力场中的热力学规律,给出重整热力学理论的方案,该方案涉及到热力学第二定律、第零定律、热流定律。重整后的热力学定律更具普适性。     

Power law and small world properties in a comparison of traffic city networks

We analyze the statistical properties of the urban public bus networks of two cities (Beijing and Chengdu) in China. To this end, we present a comprehensive survey of the degree distribution, average path length, and clustering of both networks. It is shown that both networks exhibit small world behavior and are hierarchically organized. We also discuss the differences between the statistical properties displayed by the two networks. In addition, we propose a weight distribution approach to study the passenger flow through the public bus networks we considered. A hierarchical structure is observed here also.
