今天上了第一节课,介绍了课程讲了两个算法,感觉这个老师还是很棒的。
充满激情。。上课到忘我的时候都一直闭着眼睛。
下课后的感觉就是在知识的海洋中遨游了三个小时~~~
印象最深的是三个片段:
1.他说compression和searching都是很无聊的东西,但是searching compressed后的data就变得很有趣了。
2.他说我门的tutorial没有tutor。。 因为他说没办法这门课不知道找不到tutor,哈哈
3.讲到Huffman Tree的时候,他一直在抱怨这个想法这么简单,要是自己早出生两百年,说不定,。。。
很有趣 很有激情的一个香港老师,虽然说话有口音,但是还是能听懂90%,还是没有障碍的。

好喜欢这门课,三个小时真的很享受思考的感觉。
这周讲了Adaptive Huffman Tree和 BWT压缩算法。
可能还有一个原因是这个老师很幽默,会穿插一些段子还挺搞笑的。

这周讲了两个文本搜索算法,但没有听懂,唯一一门跟的上老师的课也沦陷了,哎~
明天早起复习一下好了,今天真的好累。
花了太久写assignment1了,虽然写出了一些东西,但~

Week 4:
Having taught some strange searching algorithms, got the idea of the procedure,
but totally cannot understand how it works.
Assignment 1:
almost done the encoding, but have no idea of the in maintaining Vitter’s invariant.

Week 4(holiday):
Assignment 1:
Having completed the encoding and decoding!!! cheers~

Week 6:
Assignment 2:
The assignment2.. Backward BWT search…
I did everything, made a lot of improvement, but my program is still so slow…
but anyway, I tried my best, proud of myself.
It so hard and fun to improve efficiency of a program.

Week 8:
About the marking of assignment2.. So moved that Raymond forgiven my mistake.
He is so strict and has his own principles, but is also an extremely nice person, full of emotion.

Week 10:
WOW, it’s week 10 now!! Too busy to update the blog.
Just submitting the assit2, I am struggling in assit3 UU.
Today, in the lecture, Raymond showed the name of the fastest guy of assit2,
Although fastest is not always good.. haha, I really admin this encouraging behaviour and this awsome person.

Week 11:
Made silly mistake again…
but Raymond is so kind.
The assit3 is almost done now, much easier than assit 1 and 2.
When I am writing README file and thinking that if Raymond can give each student some feedbacks, it will be great.


2016/05/19

Assit3 done.
I used the Boyer Moore Algorithm without index and the efficiency is not bad.

Perfect mark of assignment3:

Last lecture
Thanks Raymond!

Fianl Exam
2 hours before final exam, best wishes to myself.
And this is my cheating sheet, a piece of art!

Although most of the questions were on the exercises provided,
some of them is tricky and not easy to solve.
