Outline (in English)
We study Functional Programming and Category Theory.
Students will be expected to have completed the required assignments after each class meeting. Your study time will be more than four hours for a class.
Your overall grade in the class will be decided based on the following
Final presentation: 50%、Short reports : 50%.
授業で使用する言語Default language used in class
日本語 / Japanese
授業の概要と目的（何を学ぶか）Outline and objectives
We study Functional Programming and Category Theory.
到達目標Goal
Students will acquire working knowlege of category theory via programming with Haskell. Basic notions such as functors, natural transformations, adjoints, Kleiski triples, and monads are fully explained.

授業の進め方と方法Method(s)（学期の途中で変更になる場合には、別途提示します。 /If the Method(s) is changed, we will announce the details of any changes. ）
After basic materials are presented, students are asked to write Haskell code to implement abstract concepts according to concrete examples. You are required to present your code approximately once in four class meetings. Feedback is directly given in the discussion at the presentation meeting.
