A Simple Algorithm for Multiple-Source Shortest Paths in Planar Digraphs

Debarati Das, Evangelos Kipouridis, Maximilian Probst Gutenberg +1

Given an $n$ -vertex planar embedded digraph $G$ with non-negative edge weights and a face $f$ of $G$ , Klein presented a data structure with $O (n lo g n)$ space and preprocessing tim…

A Linear-Time $n^{0.4}$ -Approximation for Longest Common Subsequence

Karl Bringmann, Vincent Cohen-Addad, Debarati Das

We consider the classic problem of computing the Longest Common Subsequence (LCS) of two strings of length $n$ . While a simple quadratic algorithm has been known for the problem fo…
