摘要
In this correspondence, we describe a heuristic method for the construction of linear codes with given parameters n, k, q, and a prescribed minimum distance of at least d. Our approach is based on a function estimating the probability that a code of dimension k and blocklength n' < n over G F (q) is extendable to a code with the given properties. Combining this evaluation function with a search algorithm, we were able to improve 40 entries in the international tables for the best known minimum distance in the cases q = 2 5 71 9 and found at least two new optimal linear codes.
