Eulerian disjoint paths problem in grid graphs is NP-complete

We show that the edge disjoint paths problem is NP-complete in directed or undirected rectangular grids, even if the union G + H of the supply and the demand graph is Eulerian.

The edge-disjoint paths problem is NP-complete for series-parallel graphs

Many combinatorial problems are NP-complete for general graphs. However, when restricted to series–parallel graphs or partial k-trees, many of these problems can be solved in polynomial time, mostly in linear time. On the other hand, very few problems are known to be NP-complete for series–parallel graphs or partial k-trees. These include the subgraph isomorphism problem and the bandwidth probl...

The Edge-Disjoint Paths Problem is NP-Complete for Partial k-Trees

Many combinatorial problems are NP-complete for general graphs, but are not NP-complete for partial k-trees (graphs of treewidth bounded by a constant k) and can be efficiently solved in polynomial time or mostly in linear time for partial k-trees. On the other hand, very few problems are known to be NP-complete for partial k-trees with bounded k. These include the subgraph isomorphism problem ...

Greedy Edge-Disjoint Paths in Complete Graphs

The maximum edge-disjoint paths problem (MEDP) is one of the most classical NP-hard problems. We study the approximation ratio of a simple and practical approximation algorithm, the shortest-pathfirst greedy algorithm (SGA), for MEDP in complete graphs. Previously, it was known that this ratio is at most 54. Adapting results by Kolman and Scheideler [Proceedings of SODA, 2002, pp. 184–193], we ...

An NP-Complete Problem in Grid Coloring

A c-coloring of Gn,m = [n] × [m] is a mapping of Gn,m into [c] such that no four corners forming a rectangle have the same color. In 2009 a challenge was proposed via the internet to find a 4-coloring of G17,17. This attracted considerable attention from the popular mathematics community. A coloring was produced; however, finding it proved to be difficult. The question arises: is the problem of...
