  • You can use servers provided by the university through ssh.

How to work on your assignments?

​

  • Because you cannot use the machine in E42 in the first week.
  • The assignment deadlines of the 1st and 2nd class are extended until Oct 11.
  • But I recommend you try to use university server or you set up an environment on your computer.
    • Most unix-based computer has c compiler.
    • Windows: you can use mingw (https://shorturl.at/bFSY3).

Why this course is important?

  • This is the fundamental course for advanced courses in your 3rd and 4th years.
    • C -> システムプログラミング実験、連続系アルゴリズム
    • Scheme -> 関数・論理型プログラミング実験、プロセッサ・コンパイラ実験
    • Assembly -> プロセッサ・コンパイラ実験
    • Python -> 統計的機械学習
  • So it is very important for you to practice and finish your assignments on your own.
    • It is ok to discuss and learn from each other.
    • DO NOT COPY others code.

Regarding the use of LLMs

  • As you probably know, recent LLM (e.g., ChatGPT, Gemini, Claude, and others) can do programming as well.
  • However, given the importance of this course as we just mentioned, we encourage you NOT to use LLMs to answer assignments in this course.
  • We will randomly compare your submitted code with the answer provided by LLMs.
    • If they are very similar, it is possible that we will consider your code as plagiarism.
