论文摘要
在本文中,我们介绍并调查了二进制自动划分代码的邻里。我们证明,没有比相同长度的最佳II类型代码更好的I类型代码。此外,我们为存在单一的$(56,28,12)$ - 代码和双重$(72,36,16)$ - 代码提供了一些新的必要条件。
In this paper, we introduce and investigate the neighborhood of binary self-dual codes. We prove that there is no better Type I code than the best Type II code of the same length. Further, we give some new necessary conditions for the existence of a singly-even $(56,28,12)$-code and a doubly-even $(72,36,16)$-code.
