摘要
结合遗传算法中的交叉和变异操作,文章给出了非线性等重码(n,d,w)的组合结构和构造方法.此方法对码间最小距离d=4的(n,4,w)码的构造十分有效,得到了(n,4,w)码最大容量A(n,4,w)的几个精确值和较好的上界.
Comdining with operations of cross and variation, the combinatorial construction and the construction for nonlinear equal weight code were gived.The construction methods which have been given are fully effective for the(n,4,w)-codes,some exact values and new upper bounds of A(n,4,w) were got.
