Discrete Mathematics Labolatory
Let’s explore the wonders of points and lines
We conduct research on the graph theory or the structure of shapes connected by several points and sides. For example, a shape called “graph” can be regarded as an abstract of a route map if we assume stations as “points” and routes as “sides.” This theory is applied to various mathematical sciences and engineering tasks and serves as one of the most basic computer science theories. We are also studying about how efficiently we can stuff things into a container while developing mathematics teaching materials.
