Steiner树优化问题的算法研究综述OA北大核心CSTPCD

The optimal Steiner tree problem(STP)is a classical combinatorial optimization problem,and many engineering problems can be summed up as optimal Steiner tree problems.STP is widely used in communication networks,circuit design,VLSI design,and other fields.However,the STP is a typical NP hard problem,and there is no precise polynomial time algorithm to solve it.Currently,the algorithms for solving this problem mainly focus on heuristic based approxima-tion algorithms,intelligent optimization algorithms,and belief propagation algorithms,and have achieved good results.By sorting out the principles,performance,accuracy,and other aspects of these algorithms,the advantages and disadvan-tages of the algorithms are summarized,and the research direction and algorithm design path for STP are pointed out,which has guiding significance for the research of related issues.
