Construction of Randomness Testing Based on T-Codes

Abstract (in Japanese) (See Japanese page) 
(in English) We propose a new randomness test based on T-Codes.
T-Codes are variable-length self-synchronization codes introduced by Mark Titchener in 1984. A given sequence is related to a T-Code set by T-decomposition, and it is decomposed into sub-sequences called T-prefixes which are a series of parameters obtained by a recursive construction algorithm of the T-Code set. In our test, the number of the sub-sequences called T-complexity is used.
Furthermore, we propose a new T-decomposition, which can determine the T-prefixes from the beginning to the end of a sequence, and an efficient algorithm of the new T-decomposition by using a tree structure. Reducing the computation time of the T-decomposition, this algorithm makes our new test suitable for practical use in the sense of computational complexity. The validity of our test is also verified by the empirical distribution of T-complexity and P-value.
