Education

The University of Tokyo

Electrical Engineering and Information Systems, Graduate School of Engineering
Master of Engineering

Studied evolutionary computation and published three refereed papers. Supervised by Dr. Hitoshi Iba and Dr. Danushka Bollegala and closely worked with Dr. Yoshihiko Hasegawa.

Apr. 2011 - Mar. 2013

Tohoku University

Information and Intelligent Systems, School of Engineering
Bachelor of Engineering

Learned electrical engineering and computer science. The capstone project was the development of relational database integration features of SML#, which is an extension of Standard ML. The project supervisors were Dr. Atsushi Ohori, Dr. Katsuhiro Ueno, and Dr. Akimasa Morihata.

Apr. 2007 - Mar. 2011

Demo

Ant colony optimization algorithm (ACO) applied to traveling salesman problem (TSP)

Visualize the shortest possible route (red and yellow) and pheromones (green) at each population. See it adaptively works for dynamic nodes by dragging city positions. Developed when I was a student at Iba lab.
Links to Iba lab: Executable .jar / Manual (in Japanese)

Execute on your local machine with Java Runtime Environment (JRE). Should run on Windows and Mac.
