| Research Abstract |
In this research, I succeeded to solve some combination optimization and build the methodology that could generate efficient algorithm to solve those problems automatically. Furthermore, for a small k, say one (trees) or two (series-parallel graphs), it succeeded to develop polynomial-time algorithm for solving many combination problem. Inspection of effectiveness of the technique was possible theoretically. In this research, I have published 8 journal papers and 3 international conference papers. As a result of having been provided, I give a design theory of linear-time algorithms. Its impact in a field of a linear-time algorithm theory is very important.
