匹配和网络流的量子算法
Quantum Algorithms for Matching and Network Flows
摘要:
我们提出了量子算法,用于以下图形问题:在时间O内找到最大二分匹配(n sqrt{m+n} log n),在时间O内找到一个极大非二部匹配(n^2(sqrt{m/n} + log n)log n)的整数网络的最大流(min(n^{7/6} sqrt m * U^{1/3},sqrt{n U} m)log n),其中n是顶点的数目,m是边的数目,并且U <= n^{1/4}是边的容量的上界。
英文摘要:
We present quantum algorithms for the following graph problems: finding a maximal bipartite matching in time O(n sqrt{m+n} log n), finding a maximal non-bipartite matching in time O(n^2 (sqrt{m/n} + log n) log n), and finding a maximal flow in an integer network in time O(min(n^{7/6} sqrt m * U^{1/3}, sqrt{n U} m) log n), where n is the number of vertices, m is the number of edges, and U <= n^{1/4} is an upper bound on the capacity of an edge.
