在现有生成伪随机序列的方法中,产生的伪随机序列存在均衡性、游程特性不够好的问题。根据随机序列的统计特性,在骑士巡游问题 SemiHam 求解算法的基础上,提出了基于随机序列统计特性的伪随机序列生成方法。首先,对棋盘中的格子设定不同长度的0、1游程值;然后,再用骑士巡游问题SemiHam求解算法产生的Hamilton圈对设定游程值的棋盘进行扫描;最后,取出0、1游程值,得到伪随机序列。实验结果表明,该算法产生的伪随机序列满足随机序列统计特性,且随机性较好。
There are some problems existing in pseudo-random sequence generating methods
such as the weaker proportionality
bad run length characteristic
etc. Hence
based on the SimiHam algorithm in Knight's tour problem
a pseudo-random sequences generating method was proposed according to the statistical properties of random se-quence. First
set runs value 0 and 1 in different length for the grids in chessboard
and then scan the chessboard with Hamilton cycles which are generated by SemiHam algorithm in Knight's tour problem
At last extract run length values of 0 and 1 and get the pseudo-random sequences. Experimental results show that the pseudo-random se-quence generated by the proposed algorithm satisfies the statistical properties of a random sequence and has better randomness.
