在计算机通信网络建设过程中,通信主干网的高可靠性一直是广大设计者和用户所关心的重大问题,分析了通信主干网的全终端可靠性优化设计问题,针对一种典型可靠性优化模型,分别设计了用于求解该模型的改进遗传算法、模拟退火算法、改进蚁群算法以及改进粒子群算法,并对该模型进行了优化求解,计算机仿真实例表明:粒子群算法在算法的优化质量和收敛速度上都优于其它三种算法,能够取得满意的优化结果,具有一定的实用价值。
In the construction process of computer communication network, the reliability of communication backbone network is cared by vast designers and users, All-terminal reliability optimization design of communication backbone network is analyzed. A typical reliability optimization model is solved by improved GA, SA, improved ACO and improved PSO respectively. Computer simulation shows that the PSO can get a better effect than the other three algorithms.
