2. Warnings Before (Signing for) the Course (1/3)
Goal of NTU DSA class
As good as the best ones in the world
Tentatively, 6 homework sets, midterm exam, final project
About homework
Including writing assignments and time-consuming programming assignments
HW1 is to be announced next week
Warning: High expectations  Be prepared to work hard!

3. Warnings Before (Signing for) the Course (2/3)
Will you give me a second chance if I copy homework from other people? No.
Could you let me pass because I will be kicked out by the ½ rule? No.
Will you change my score from F to C? No.
Warning: Strict instructor  Be prepared to follow the rules!

4. Warnings Before (Signing for) the Course (3/3)
We are veterans
HT: Fifth-time teach the course
Roger: Fourth-time teach the course
But we are ambitious and willing to experiment with different ways for effective learning.
How many people will not pass?
Not known yet.
Will your investment get good return (knowledge)?
No guarantees, but we’ll try our best.
Warning: Uncertain outcome  Be prepared to take some risks!

5. Wise Words
給資訊系的同學們：努力加油！
給想加選的外系同學們：審慎考慮！

6. Some Historical Notes Around 1997 Starting 2001 Starting 2010
「計程」有兩學期，上學期教 C，下學期教 C++
大二上學期教「資料結構」
大二下學期教「演算法」
Starting 2001
「計程」變成一學期，大一下學期教「物件導向程式設計」
大二上學期教「資料結構與演算法上」
大二下學期教「資料結構與演算法下」
Starting 2010
物件導向程式設計變為選修
大一下學期教「資料結構與演算法」
大二上學期教「演算法設計與分析」

7. Reasons 兩學期的「計程」變成一學期、「物件導向程式設計」 變成選修：相信同學們可以有自己學習不同語言的能 力。
把「資料結構」及「演算法」合成一門課：兩者互相 依賴，其實不容易分散來教。
把「資料結構與演算法上/下」區分成「資料結構與演 算法」和「演算法設計與分析」：強調前者以實作為 主，銜接計程做更深入的程式練習；後者以分析為主， 建立在前者的基礎上以探討更多不同的演算法。

8. Course Descriptions Goal A program is…
Use software to synergize two resources effectively
Computation: CPU, GPU
Storage: memory, disk, network
A program is…
Algorithms + Data Structures = Programs

11. Textbook and Prerequisites
Textbook: Data Structures and Algorithms in C++, 2nd Edition by Goodrich, Tamassia and Mount.
Please get it as early as possible since we have reading assignments
Learning to read a text book is part of the course
NTU Library: reserved copy in the shared course material area
Prerequisites
C: required
C++: preferred

12. To Keep Two Classes Sync’ed
To keep these two DSA classes equivalent (and make it fair), we will try to keep (almost) everything the same, including textbook, homework, midterm exam, final project, grading formula, TAs, schedule, etc.
So what’s the difference?
HT’s class is in English
Roger’s class is in Mandarin
So…
You don’t need to switch between these two classes.
You are welcome to attend any class at any time.

13. More about the Instructors
Both instructors are strict but friendly, and willing to help...
Will you repeat the previous code/slide? Yes!
Will you discuss with me after class if I don’t understand? Yes!
Will you pardon my silly questions? There is no silly questions at all!
Feel free to ask the instructors and give feedbacks!

14. About Enrollment
Both instructors welcome extra enrollment, up to the limit of the classroom. (Type-3)
Auditing is also welcome.
Think before you choose to enroll.
If you have chosen to do so, welcome aboard!

15. Very friendly TAs. Be sure to ask them questions!
About TAs
List of TAs (tentatively):
Graduate student: 黃冠豪
Undergraduates: 宋彥頡、林天翼、陳步青、鍾毓安、鍾詠先、林于智、沈亮欣、劉承昌、周紀寧
for TAs:
All the TAs and instructors will receive s sent to this account.
It is usually faster than sending to individual.
Office hours for TAs: to be announced.
Very friendly TAs. Be sure to ask them questions!

16. Policy of fairness How important is fairness?
For monkeys
Our ultimate policy of fairness
Taking any unfair advantages over other class members is not allowed
It is everyone’s responsibility to maximize the level of fairness.
This applies to instructors, TAs, and students.
No cheating!
No lying!
No plagiarism!

17. Grading Policy 10% for participation 90%
2% each for in-class or on-forum (FB) questions/asnwering
90%
Homework: 45% or so
Midterm exam: 20% or so
Final project: 25% or so
The final grades are based on both scores and rankings
The instructors reserve the rights to
Adjust percentages of each categories
Determine the way to combine scores and rankings

18. About Homework (1/2)
Homework discussions are encouraged, but students should have their own write-ups alone and understand them fully.
References (books, notes, Internet) can be consulted, but not copied from.
Lending/borrowing homework is strictly prohibited!
Deal? If your classmate wants to borrow homework from you, what do you say?

19. Four penalty-free late half-days (金牌) per person.
About Homework (2/2)
No individual extension allowed unless for legitimate reasons notified in advance
Overdue penalty for homework
90% discount for overdue of 0-12 hours
80% discount for overdue of hours …
Four penalty-free late half-days (金牌) per person.

20. Reading Assignments Weekly reading assignments
Sections related to what we teach
Sections that are worth reading by yourself
3/6: 3-hour teaching, 6-hour reading/writing after class
Some of the reading material may show up in exams
We cannot teach the whole book, but with reading you can learning it all.

21. How to Pass the Class? Golden rules to pass the class
