用遗传算法求解二元线性分组码的权计数器

Genetic algorithms for finding the weight enumerator of binary linear block codes

Said Nouh, Mostafa Belkasmi

摘要:

本文提出了一种用遗传算法求解二元线性分组码的重量计数器的新方法。这种方法包括在寻找二进制重量枚举的代码和它的对偶,并创建从著名的麦克威廉姆斯身份的线性系统(S)的整数变量,我们添加所有已知的信息从结构的代码。自同构群的一些子群的知识,在此代码保持不变,允许给强大的限制的解决方案(S)和近似的重量枚举。通过应用这种方法,并通过使用的稳定性的扩展二次剩余码(ERQ)的投影特殊线性群PSL2,我们找到了所有可能的值的重量枚举长度为192和200的两个ERQ码的列表。我们还对这两个枚举器的真实值进行了很好的近似。

英文摘要:

In this paper we present a new method for finding the weight enumerator of binary linear block codes by using genetic algorithms. This method consists in finding the binary weight enumerator of the code and its dual and to create from the famous MacWilliams identity a linear system (S) of integer variables for which we add all known information obtained from the structure of the code. The knowledge of some subgroups of the automorphism group, under which the code remains invariant, permits to give powerful restrictions on the solutions of (S) and to approximate the weight enumerator. By applying this method and by using the stability of the Extended Quadratic Residue codes (ERQ) by the Projective Special Linear group PSL2, we find a list of all possible values of the weight enumerators for the two ERQ codes of lengths 192 and 200. We also made a good approximation of the true value for these two enumerators.
