依据遗传算法理论,在配水求解中,摈弃传统的二进制编码,采用了和人们处理问题思路一致的十进制编码,针对遗传算法的某些局限性,采用自由搜索算法克服了传统基因编码方法容易陷入局部最优解的缺陷,扩大了算法的搜索空间,从而提高了基因序列的质量；同时由于对各个渠道流量调节采用了自由搜索算法,使各渠道的流量在其允许的范围内调节到最佳值,从而使各个渠道在同一时间关闭,不但减少了渠道弃水,而且在目前灌区的管理条件下还减少了人工管理的劳动时间.%According to the genetic theory, it is essential to discard the traditional binary system coding for solving water distribution. Considering GA sinking into the partial solution easily, free search algorithm is introduced. It extends the search space for algorithm, enhancing the quality of gene coding, adjusting the discharge of canal, making every canal close at the same time, decreasing the discarding water of canal, and reducing the time of manual work.
