1.13 Errata and Addenda for Vol. 22a,t, determine a basis of minimum cost among those with . red elements, or decide that no such basis exists. In this paper, we investigate possible extensions of this result from ordinary matroids to the more general notion of .. Poset matroids (also called .) are defined on the collection of all idea

Reducing the Clique and Chromatic Number via Edge Contractions and Vertex Deletions,ict the input graph . to some special graph class. We continue a line of research that considers these problems for subclasses of perfect graphs, but our main results are full classifications, from a computational complexity point of view, for graph classes characterized by forbidding a single induced connected subgraph ..

The Parity Hamiltonian Cycle Problem in Directed Graphs,on when a directed graph has a PHC, and shows that the PHC problem in a directed graph is solved in polynomial time. The characterization, unlike with the undirected case, is described by a linear system over GF(2).
