| Outline of Final Research Achievements |
We proposed an algorithm to find the maximum detour hinge vertex on an interval graph that runs in $O(n2)$ time, where $n$ is the number of vertices in the graph. This result was accepted in Institute of Electronics, Information and Communication Engineers.
We proposed an algorithm that identifies the maximum detour hinge vertex on a permutation graph in $O(n2)$ time, where $n$ is the number of vertices in the graph. This result was accepted in Institute of Electronics, Information and Communication Engineers.
We presented an algorithm that takes $O(n+m)$ time to solve the FVS problem in a normal Helly circular-arc graph with $n$ vertices and $m$ edges. We presented our paper at the 24th Fuzzy, Artificial Intelligence, Neural Networks and Computational Intelligence.
