摘要

本文给出了一种计算卷积码自由距离的快速算法．该算法把遗传算法与模拟退火有机结合，并根据随机概率来控制算法的运行，避免了优化迟钝与盲目现象，提高了该算法的收敛质量和速度．模拟结果也表明：与已有算法相比，本算法具有更好可靠性、有效性和稳定性

Abstract

A fast optimal algorithm is presented for computing the free distance of convolutional codes.The designation of a fast algorithm is based on the good combination of Genetic Algorithm with Simulated Annealing.With the advantageous properties of higher speed and better quality

this algorithm can avoid the phenomena of bluntness and blindness which have occurred in paper [1].A comparison is made by simulation to show these better performances than those in [1].
