摘要:

Steiner树问题(STP)是一个著名的NP难组合优化问题,广泛应用于网络设计、集成电路布局、生物信息学等领域。然而,传统算法在处理大规模STP实例时往往难以在效率和解质量之间取得平衡。在本文中,我们提出了一种新的基于量子退火的算法来解决STP问题:我们首先将STP建模为适用于量子退火的二次无约束二元优化(QUBO)形式,然后设计相应的编码策略,最后通过实验测试验证该算法。结果表明,我们的基于量子退火的方法可以在中等规模的STP实例中以相对较低的计算开销获得高质量的解,为解决这一难以处理的组合优化问题提供了新的可行路径。

英文摘要:

The Steiner Tree Problem (STP) is a well-known NP-hard combinatorial optimization problem, which has wide applications in network design, integrated circuit layout, bioinformatics, and other fields. However, traditional algorithms often struggle to balance efficiency and solution quality when dealing with large-scale STP instances. In this paper, we propose a new quantum annealing-based algorithm for solving the STP: we first model the STP into a quadratic unconstrained binary optimization (QUBO) form suitable for quantum annealing, then design a corresponding encoding strategy, and finally verify the algorithm through experimental tests. The results show that our quantum annealing-based method can obtain high-quality solutions with relatively low computational overhead for moderate-scale STP instances, providing a new feasible path for handling this intractable combinatorial optimization problem.
