Course description and aims

The purpose of this course is to understand basic philosophies used in handling discrete information and/or discrete structure which are essential in computer and information processing, and to acquire basic methods for handling discrete information and/or discrete structure.

Student learning outcomes

Students will be able to understand the basic concepts of graph theory, and will be able to acquire basic methods for design and analysis of algorithms. Also, students will be able to understand the principle of algorithms and the relation between the property of a discrete structure and the efficiency of an algorithm, and to apply basic methods in the field of information and communications engineering.

Keywords

graph, algorithm, computational complexity

Competencies that will be developed

✔ Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

It is essential to handle discrete information and/or discrete structure in computer and information processing. This course discusses basic properties of graphs from an algorithmic point of view, and provides the basic concepts for the analysis of algorithms and basic algorithms for graphs. Also, an overview of the design methodologies for algorithm and an overview of the theory of NP-completeness are introduced. In principle, one exercise session corresponds to the previous two lectures. An exercise session includes concrete problems related to the contents of the previous two lectures and students will be able to apply the knowledge and methods acquired during the lectures to practical problems.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend a certain length of time outside of class on preparation and review (including for assignments), as specified by the Tokyo Institute of Technology Rules on Undergraduate Learning (東京工業大学学修規程) and the Tokyo Institute of Technology Rules on Graduate Learning (東京工業大学大学院学修規程), for each class.
They should do so by referring to textbooks and other course material.
