AboutAbout the lab
Studying combinatorial optimization around theoretical computer science.
Ono Lab conducts research centered on combinatorial optimization, in the area surrounding theoretical computer science and operations research.
The lab is part of the Department of Mathematical Informatics, Graduate School of Informatics, Nagoya University, and belongs to the Foundations of Mathematical Informatics group.
At the undergraduate level, it corresponds to the Mathematical Informatics course of the Department of Natural Informatics, School of Informatics.
The research areas listed for the faculty member are theory of algorithms, computational complexity, approximation algorithms, and parameterized algorithms.
From 2010 through fiscal 2016, the lab was active at the Faculty of Economics, Graduate School of Economics, Kyushu University, and since fiscal 2017 it has been active at the Graduate School of Informatics, Nagoya University.
Key terms
- Combinatorial optimization
- A field that deals with the problem of choosing the best option, under given conditions, from among a large number of possible choices.
- Computational complexity
- A measure of how much time or memory a procedure for solving a problem requires.
- Approximation algorithm
- A procedure that does not find the best possible answer but produces an answer close to it.
