| 摘要: |
| 基于目前各种节水灌溉制度优化方法存在的不足，本研究将混沌优化算法运用于作物灌溉制度优化设计中。由于混沌优化算法的叠代具有不重复性和遍历性，因此该算法可以避免陷入局部最优点而获得全局最优。实例计算分析表明，与遗传算法、动态规划逐次逼近法相比，混沌优化算法具有原理简单、计算简便、结果精度高的优点。 |

| The application of chaos algorithm in optimal design of water-saving irrigation program |
|
|
| Abstract: |
| Based on the deficiency of common optimal methods of water-saving irrigation program ,the paper applies chaos algorithm to the optimal design of irrigation program of crops. Based on the congruence non-repetition and ergodicity of chaos ,the method will avoid the local optimal solution and find satisfactory globe optimal solution. Finally, the paper compares chaos algorithm with genetic algorithm and dynamic programming successive approximation in detail and the outcome indicates that the method is simple ,convenient and accurate. |
