Today I was able to finish L4,L5,L6 of the 15-455 course. L5 and L6 slides can be understood effortlessly, perhaps the course isn’t that hard after all.

No homework is done today due to participation in algorithmic competition. I will not participate in algorithmic competition seriously anytime soon. Study comes first.

Best case scenario: 15-455 finished before next Wednesday, 15-855 finished before 3/1. Additional material and papers(?) are learned.

Worst case scenario: 15-455 finished before next Sunday, 15-855 finished 80% before 3/1. No additional materials learned.

Self learning reports will be posted every day before 24:00 to keep me on track.

Today I was only able to finish L03 and 2/3 of L04 of 15-455. No homework is done.

This is due to an algorithmic competition which I had to participate. Tomorrow I hope to:

1. Finish L04
2. Finish the homework.
3. Finish L05
4. Finish L06 (Not likely as I have to participate in algorithmic competition tomorrow too.)

I decided to learn http://www.cs.cmu.edu/~15455/ first, before progressing to the graduate course by Ryan O’Donnell.

As I have learned most of the material before, I have plenty reason to believe that I will finish with 15455 soon.

Yet today I found the course to be more difficult than I imagined while doing the first assignment. The course by K. Sutner offers more material than the textbook offers and the course can probably provide me a deeper understanding of the material, so I decided to put effort in it to finish it soon.

I promise myself to never see the solution while attempting the homework. Only when I give up will I see the solution.

Today I learned the first two lectures and finished the first Assignment. I expect to learn more efficiently in the following days.

I am a 2nd-year undergraduate student from China who is interested in theoretical computer science, especially in circuit lower bounds and pseudo-randomness.

I am currently self-learning computational complexity and other theoretical computer science topics actively.

I also participate in competitive programming, which is a great fun. I have won the 1st place in ICPC Shanghai 2020 and CCSP 2020.

成就系统里面好像没有更多可以获得的区域赛成就了，还可以获得的其他成就有：上分网站的成就，WorldFinals的成就。。。

难度自适应系统总算工作一回。。。

摘要：在上海区域赛拿到了冠军

今天如果不FST能上95分，最后却下了118分。感觉分稍微不低了之后打CF的感觉就只是在和其他选手卷了。

感到自己打算法竞赛还是大有前途的啊，但是我也不知道我还能再打多长时间了。如果能积极的学习，打出比较好成绩的话，还是可以继续打的啊……

我感到，“退役”并不可怕，不退役却又不能拿精力提高水平和表现才可怕。退役需要人决定放弃，而划水只需要“划水”。划水做老年选手，不积极学习，打不出好成绩却拿算法竞赛浪费时间是不可取的。

希望在有朝一日能上到3000分，成为LGM。感到自己还有未发挥的潜力却决定不打算法竞赛，我恐怕是做不到的。

唉，累了，题是好题，做出此题感觉还是不错的，只是没时间写题解了。

也没时间打算法竞赛了，周末还要磨锤子。我好难啊。

也没时间写作业了。

也没时间睡觉了。

但是希望周日还是能上分，毕竟人，要有梦想

差一点点夺冠了？？？还是差多？？？不懂。。。反正好像差4byte就过另一个题了。感觉我的代码水平还行，而且队友实在是太行了。。

这次ccpc让我对线上赛有所改观，我觉得线上赛可能有人作弊对可能拿杯选手造不成什么影响，所以挺好的，只是不能旅游，但其实也没啥可旅游的。。。

感觉线上赛有一个好，就是不需要交通，节省时间，节省精力。希望ICPC能好好发挥，顺利出个线。。希望在退役之前拿个区域赛冠军啊。。。

啥时候杯邮寄过来啊。。不懂。。

好像博客被我滥用了，根本不更新干货了。。我能怎么办，干货生产太难了，还是水博客容易
