Algorithms for Computing the Longest Parameterized Common Subsequence

  title={Algorithms for Computing the Longest Parameterized Common Subsequence},
  author={Costas S. Iliopoulos and Marcin Kubica and Mohammad Sohel Rahman and Tomasz Walen},
In this paper, we revisit the classic and well-studied longest common subsequence (LCS) problem and study some new variants, first introduced and studied by Rahman and Iliopoulos [Algorithms for Computing Variants of the Longest Common Subsequence Problem, ISAAC 2006]. Here we define a generalization of these variants, the longest parameterized common subsequence (LPCS) problem, and show how to solve it in O(n) and O(n+R log n) time. Furthermore, we show how to compute two variants of LCS… CONTINUE READING
