Abstract

A genetic algorithm (GA) for the Steiner Problem in a graph (SPG) is presented, and its application to global routing of VLSI layouts discussed. In this context the GA's capability to provide several distinct high-quality solutions to a given problem is very advantageous. The performance of the algorithm is compared to that of two heuristics from the literature. The GA is clearly superior in terms of result quality while also being competitive with respect to runtime.<>

图中Steiner问题的遗传算法
提出了一种求解图中Steiner问题的遗传算法,并讨论了该算法在超大规模集成电路布局全局路由中的应用。在这种情况下,GA为给定问题提供几个不同的高质量解决方案的能力是非常有利的。将该算法的性能与文献中两种启发式算法的性能进行了比较。GA在结果质量方面显然更胜一筹,同时在运行时间方面也具有竞争力
