Abstract. We study the Arc-Preserving Subsequence (APS) problem with unlimited annotations. Given two arc-annotated sequences P and T, this problem asks if it is possible to delete...
Abstract. Given two arc-annotated sequences (S, P) and (T, Q) representing RNA structures, the Arc-Preserving Subsequence (APS) problem asks whether (T, Q) can be obtained from (S,...
The Arc-Preserving Subsequence (APS) problem appears in the comparison of RNA structures in computational biology. Given two arcannotated sequences of length n and m < n, APS a...
