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.

百度關于JTAG接口的介紹。JTAG是英文“Joint Test Action group的詞頭字母的簡寫，該組織成立于1985 年，是由幾家主要的電子制造商發起制訂的PCB 和IC 測試標準。JTAG 建議于1990 年被IEEE 批準為IEEE1149.1-1990 測試訪問端口和邊界掃描結構標準。該標準規定了進行邊界掃描所需要的硬件和軟件。自從1990 年批準后，IEEE 分別于1993 年和1995 年對該標準作了補充，形成了現在使用的IEEE1149.1a-1993 和IEEE1149.1b-1994。JTAG 主要應用于：電路的邊界掃描測試和可編程芯片的在系統編程。

最近在學習Oracle，對測試人員而言必須掌握兩種語言：第一種是DML，數據操縱語言 (Data Manipulation Language) 是SQL語言中，負責對數據庫對象運行數據訪問工作的指令集，以INSERT、UPDATE、DELETE三種指令為核心，分別代表插入、更新與刪除。第二種是：DQL，數據查詢語言 (Data Query Language) 是SQL語言中，負責進行數據查詢而不會對數據本身進行修改的語句，這是最基本的SQL語句。核心指令為SELECT，以及一些輔助指令，如FROM、WHERE等，FROM：表示來源，可以搭配JOIN做鏈接查詢； WHERE：過濾條件；group BY：在使用聚合函數時用到，如SUM,COUNT,MAX,AVG；HAVING：對聚合結果進行篩選，這是和WHERE的不同點；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.
