Nobuharu Iwasawa,Koichi Narasakay requirements and two compact formulations based on network flows. For the former we implement a branch-and-cut algorithm which separates connectivity constraints. We built a test instance generator, partially based on publicly-available real world data, in order to compare empirically the three formulations.

Small Ring Compounds in Organic Synthesis VIplittable congestion game with at least three players and non-matroidal set systems per player, there is an isomorphic game having multiple equilibria. Our results leave a gap between base orderable matroids and general matroids for which we do not know whether equilibria are unique.

1.13 Errata and Addenda for Vol. 22a, polynomially solvable. In this work, we first prove that .PF is NP-complete for bipartite graphs, as .LP is known to be. We also obtain new graph classes where the complexity of these problems would coincide.

1.13 Errata and Addenda for Vol. 22a,base polytopes of matroids. For the latter family, we also give a simple description of the facet-defining inequalities. These results are achieved by an investigation of related combinatorial objects, that could be of independent interest.
