Traveling Salesperson Problem Our branch-and-strategy splits a branch and bound solution into two groups: one group including a particular arc and the other excluding this arc. 1.Each splitting incurs a lower bound and we shall traverse the searching tree with the "lower" lower bound. 2.If a constant subtracted from any row or any column of the cost matrix, an optimal solution does not change.

PhD research, you have already made a decision that will have a major impact on the success of your project, and perhaps even on your future career. You have chosen to work in a particular research group, under the guidance of a particular thesis advisor or supervisor.

It’s your first day in the lab.Undoubtedly you are experiencing a range of emotions: excitement, curiosity, anxiety. You will be working in this lab and with a group of people, as well as with your supervisor, for several years to come. This is the first day of a long commitment and, for some, a hard road ahead. Which is why it’s important to get off on the right foot.

Before you even get started on your PhD research, you have already made a decision that will have a major impact on the success of your project, and perhaps even on your future career. You have chosen to work in a particular research group, under the guidance of a particular thesis advisor or supervisor.

百度关于JTAG接口的介绍。JTAG是英文“Joint Test Action group的词头字母的简写，该组织成立于1985 年，是由几家主要的电子制造商发起制订的PCB 和IC 测试标准。JTAG 建议于1990 年被IEEE 批准为IEEE1149.1-1990 测试访问端口和边界扫描结构标准。该标准规定了进行边界扫描所需要的硬件和软件。自从1990 年批准后，IEEE 分别于1993 年和1995 年对该标准作了补充，形成了现在使用的IEEE1149.1a-1993 和IEEE1149.1b-1994。JTAG 主要应用于：电路的边界扫描测试和可编程芯片的在系统编程。

最近在学习Oracle，对测试人员而言必须掌握两种语言：第一种是DML，数据操纵语言 (Data Manipulation Language) 是SQL语言中，负责对数据库对象运行数据访问工作的指令集，以INSERT、UPDATE、DELETE三种指令为核心，分别代表插入、更新与删除。第二种是：DQL，数据查询语言 (Data Query Language) 是SQL语言中，负责进行数据查询而不会对数据本身进行修改的语句，这是最基本的SQL语句。核心指令为SELECT，以及一些辅助指令，如FROM、WHERE等，FROM：表示来源，可以搭配JOIN做链接查询； WHERE：过滤条件；group BY：在使用聚合函数时用到，如SUM,COUNT,MAX,AVG；HAVING：对聚合结果进行筛选，这是和WHERE的不同点；ORDER BY：排序。

To locate the theory of Lie groups within mathematics, one can say that Lie groups are groups with some additional structure that permits us to apply analytic techniques such as differentiation in a group theoretic context.
