Linear Least-Squares Algorithms for Temporal Difference Learning

We introduce two new temporal difference (TD) algorithms based on the theory of linear least-squares function approximation. We define an algorithm we call Least-Squares TD (LS TD) for which we prove probability-one convergence when it is used with a function approximator linear in the adjustable parameters. We then define a recursive version of this algorithm, Recursive Least-Square TD (RLS TD). Although these new TD algorithms require more computation per time-step than do Suttons TD() algorithms, they are more efficient in a statistical sense because they extract more information from training experiences. We describe a simulation experiment showing the substantial improvement in learning rate achieved by RLS TD in an example Markov prediction problem. To quantify this improvement, we introduce the TD error variance of a Markov chain, TD, and experimentally conclude that the convergence rate of a TD algorithm depends linearly on TD. In addition to converging more rapidly, LS TD and RLS TD do not have control parameters, such as a learning rate parameter, thus eliminating the possibility of achieving poor performance by an unlucky choice of parameters.

A New Algorithm To Solve Vehicle Routing Problems (VRPs)

Efficient Resource management has a direct influence on business performance and profitability. Vehicle Routing Problems (VRPs) considered in this paper are resource management problems where the aim is to use the limited number of resources to a large number of jobs so that the maximum number of jobs can be completed with minimum cost. A VRP consists of a workforce of maintenance engineers and a set of geographically distributed customers requiring certain services. The problem is complicated by incorporating certain technological and temporal constraints. The objective is to maximize the amount of work done measured in terms of total number of jobs completed and to minimize the total distance travelled by all the engineers. The solution to a VRP is a list of engineers and for each engineer a tour consisting of an ordered list of services to be completed by him under the given constraints. These Problems belong to the class of NP-Complete problems. The stochastic techniques such as Hill-Climbing (HC), Tabu Search (TS), Genetic Algorithms (GA) and Simulated Annealing (SA) are found to be suitable for solving these problems efficiently. It is found empirically that out of these SA gives good results for VRPs. But in some cases it also gives poor quality results. This happens due to not allocating intelligently the unallocated jobs in SA in subsequent iterations. A new algorithm is proposed to solve VRPs in this paper. This is achieved by allocating unallocated jobs intelligently in SA. The proposed algorithm is tested empirically on a number of randomly generated VRPs. Three types of VRPs considered are over resourced, under resourced and critically resourced VRPs. In almost all cases, the proposed algorithm completes a large number of jobs with minimum cost in comparison with SA.     

基于工科院校背景的财务管理专业建设思路与措施

财务管理本科专业始建于1998年的财经类高校,随着社会经济发展和企业管理的需要,综合性大学和工科院校也先后设置了财务管理本科专业。针对财务管理本科专业的人才培养,不同类型高校都进行了有益的探索,由于办学背景的不同,各个高校制订的财务管理本科专业人才培养方案应具有明显差异。如何体现工科院校办学背景,彰显财务管理本科专业建设的特色,是值得工科院校财务教育专家深入研究的。本文在分析工科院校办学特色的基础上,提出了工科院校财务管理本科专业建设思路与相关措施。
