Efficient Algorithms for k -Disjoint Paths Problems on DAGs
Given an acyclic directed graph and two distinct nodes s and t, we consider the problem of finding k disjoint paths from s to t satisfying some objective. We consider four objectiv...

Finding a curve in a map
Given a polygonal curve and a geometric graph, we describe an efficient algorithm to find a path in the graph which is most similar to the curve, using the well-known Fr´echet d...

Reducing End-to-End Delay in Multi-path Routing Algorithms for Mobile Ad Hoc Networks
Some of the routing algorithms in mobile ad hoc networks use multiple paths simultaneously. These algorithms can attempt to find nodedisjoint paths to achieve higher fault toleranc...

Finding Sparser Directed Spanners
A spanner of a graph is a sparse subgraph that approximately preserves distances in the original graph. More precisely, a subgraph H = (V, EH ) is a k-spanner of a graph G = (V, E...
