| Outline of Final Research Achievements |
Milnor invariant is one of most important notions for classifying link groups in the low-dimensional topology. The invariant is, however, not easy to compute for large links. Thus, in this research, we propose a useful tool for this analysis using the grammar compression that makes us possible to compute Milnor invariant for a large depth not computable so far. We developed such a tool and supplied it to the community of researchers for discovering new knowledge of the link groups.
