Small Molecule — Protein Interactionseir only common vertex is the root node. We use Menger’s theorem to provide a characterization of all rooted graphs such that the maximum number of vertex-disjoint rooted cycles equals the minimum size of a subset of non-root vertices intersecting all rooted cycles, for all subgraphs.

Tanja Schneider-Merck,Martin Trepelive allows to apply the exact algorithm for the mono-objective vehicle routing problem of Baldacci et al. (2008). The algorithm is applied to a bi-objective VRP with time-windows. Computational results are compared with a classical bi-objective technique. The results show the pertinence of the new method, especially for clustered instances.

Isolate

The Distance Polytope for the Vertex Coloring Problem, assigned to each vertex. We show close relations between this formulation and the so-called orientation model for graph coloring. In particular, we prove that we can translate many facet-inducing inequalities for the orientation model polytope into facet-inducing inequalities for the distance model polytope, and viceversa.

We implement our algorithms and compare with brute-force approaches to show that they scale very well as the dimension and number of facets grow larger.
