Abstract (in Japanese) (See Japanese page) 
(in English) The max-fractional distance of a binary linear code is deeply related to
the performance of an linear programming (LP) decoder on the AWGN channel.
In this paper, we propose an efficient algorithm for evaluating the max-fractional distance of LDPC codes.
The proposed method is based on efficient interior point method for solving LP problems.
By using the proposed algorithm, the max-fractional distance of length up to 4000 has been successfully obtained.
