Determining Edge Expansion and Other Connectivity Measures of Graphs of Bounded Genus
In this paper, we show that for an n-vertex graph G of genus g, the edge expansion of G can be determined in time nO(g2 ) . We show that the same is true for various other similar ...

Algorithms for Effective Argumentation in Classical Propositional Logic: A Connection Graph Approach
There are a number of frameworks for modelling argumentation in logic. They incorporate a formal representation of individual arguments and techniques for comparing conflicting arg...

Fillets: Cues for Connections in Focus+Context Views of Graph-Like Diagrams
We apply fillets — smoothing of sharp angles at the joints — between the connections and nodes of graph-like diagrams. In situations where the graph layout is constrained, e....

Sharp Tractability Borderlines for Finding Connected Motifs in Vertex-Colored Graphs
We study the problem of finding occurrences of motifs in vertex-colored graphs, where a motif is a multiset of colors, and an occurrence of a motif is a subset of connected vertic...

Partitioning a Multi-weighted Graph to Connected Subgraphs of Almost Uniform Size
Assume that each vertex of a graph G is assigned a constant number q of nonnegative integer weights, and that q pairs of nonnegative integers li and ui, 1 i q, are given. One wis...
