基于String匹配框架的欧拉路径问题建模

Modelling the Eulerian Path Problem using a String Matching Framework

Dragos Trinca

摘要:

著名的欧拉路径问题可以在多项式时间内求解(更确切地说,存在一个线性时间算法)。在本文中,我们使用字符串匹配的框架模型的问题,然后开始这个问题的一个变种,称为(2,1)-STRING-MATCH问题(这实际上是一个推广的欧拉路径问题)的算法研究。然后,我们给出了(2,1)-串匹配问题的一个多项式时间算法,这是本文最重要的结果。具体来说,我们得到了Omega(n)的下界和O(n^{2})的上界。

英文摘要:

The well-known Eulerian path problem can be solved in polynomial time (more exactly, there exists a linear time algorithm for this problem). In this paper, we model the problem using a string matching framework, and then initiate an algorithmic study on a variant of this problem, called the (2,1)-STRING-MATCH problem (which is actually a generalization of the Eulerian path problem). Then, we present a polynomial-time algorithm for the (2,1)-STRING-MATCH problem, which is the most important result of this paper. Specifically, we get a lower bound of Omega(n), and an upper bound of O(n^{2}).
