| 针对概率贪婪离散粒子群算法不能兼顾收敛速度与收敛率的缺点, 提出一种基于伪幂函数的离散粒子群算法. 该方法对贪婪度函数进行伪幂化处理, 提高了较远离散位置的选择概率, 降低了较近离散位置的选择概率, 能有效避免早熟收敛, 提高收敛率. 对该算法的性能进行了分析. 无线传感网络路由优化结果表明, 该算法可以获得较好的优化结果. |
| 英文摘要 |
| Discrete particle swarm optimization algorithm based on probability greed method doesn’t provide good tradeoff between the convergence speed and the convergence percentage. To avoid this disadvantage, a new discrete particle swarm optimization algorithm is developed by introducing a pseudo power function to the greed function. The probability of choosing a far discrete position is increased; meanwhile the probability of choosing a near discrete position is decreased. Premature convergence is well avoided and the convergence percentage is enhanced. The properties of the algorithm are analyzed. Tests in route-optimization in wireless sensor networks show better results in the application of the proposed method. |
