Outline of Final Research Achievements

Size of the smallest description of a given target data is called in general Minimal Description Size (MDS), and the problem of computing MDS is called Minimal Description Size Problem (in short, MDSP). MDS is a key concept in various fields of theory of computing, such as machine learning and computational cryptography, and MDSP itself is important in Computational Complexity Theory. Unfortunately, the hardness of MDSP has been left open from early stage of discussing P≠NP conjecture. In this project, we attacked this research topic and we have obtained several breakthrough results, some of which indeed have overcome the limit of conventional hardness analyses.

Academic Significance and Societal Importance of the Research Achievements

MDSPの計算困難さはP≠NP予想の深い理解に重要な役割を持つと考えられてきたが、本研究の主要成果により、そのことが改めて明確になった。たとえ、P≠NP予想が成り立つとしても(つまり、NP問題が多項式時間計算不可能だったとしても)、NP問題の計算困難さに関しては大きく分けて4つの状況が考えられ、その間の関係が重要な課題と言われている。我々の成果により、MDSPの計算困難さがそれらの状況の関係を示す鍵となることが示されたのである。また、こうした成果を活用して、学習の計算論的な困難さの特徴付けに関しても、これまで未解決だった問題をほぼ解決する成果を得ることもできた。
