摘要：
We show how to chain maximal exact matches (MEMs) between a query string Q and a labeled directed acyclic graph (DAG) G = (V, E) to solve the longest common subsequence (LCS) problem between Q and G. We obtain our result via a new symmetric formulation of chaining in DAGs that we solve in O(m + n + k(2)|V| + |E| + kN log N) time, where m = |Q|, n is the total length of node labels, k is the minimum number of paths covering the nodes of G and N is the number of MEMs between Q and node labels, which we show encode full MEMs.
