Using Spanning Graphs for Efficient Image Registration
We provide a detailed analysis of the use of minimal spanning graphs as an alignment method for registering multimodal images. This yields an efficient graph theoretic algorithm th...

Exploring Unknown Environments
We consider exploration problems where a robot has to construct a complete map of an unknown environment. We assume that the environment is modeled by a directed, strongly connecte...

An Algorithm for Minimum Cost Arc-Connectivity Orientations
Given a 2k-edge-connected undirected graph, we consider to find a minimum cost orientation that yields a k-arc-connected directed graph. This minimum cost k-arc-connected orientat...

Flow trees for vertex-capacitated networks
Given a graph G = (V, E) with a cost function c(S) ≥ 0 ∀S ⊆ V , we want to represent all possible min-cut values between pairs of vertices i and j. We consider also the spec...
