Construction of extremal $ \mathbb{Z}_{4} $-codes using a neighborhood search algorithm
In this paper, we present a method for constructing extremal Z 4codes based on random neighborhood search.This method is used to find new extremal Type I and Type II Z 4 -codes of lengths 32 and 40.For the length 32, at least 182 new Type II extremal Z 4 -codes …
