In order to improve performances of computer communication networks, the important route selection optimization in computer communication networks is firstly studied in detail by using the modern metaheuristic search method, i. e., Tabu search, which is of great flexibility and came into use just a few years ago. Better results are obtained and compared with the traditional Lagrangean relaxation and subgradient optimization method. Especially, the superiority of this method over other algorithms is further shown in the case of very heavily loaded network. Thus, the new thinking and method are provided for the optimization theory of computer networks.

摘 要：为了改进计算机通信网络的性能，首次采用近年来才开始应用、且具有很强灵活性的现代超启发式搜索方法——Tabu搜索方法，对计算机通信网络中重要的路由选择优化问题进行了详细的研究，得到了比经典的拉格朗日松弛及子梯度优化方法更优的结果，尤其在网络负荷很重的情况下，与其它算法相比，更显示出该方法的优越性，从而为计算机网络的优化理论提供了新的思路和方法。
