Few Induced Disjoint Paths for ,-Free Graphstates that even 2-. is .-complete. We prove new complexity results for .-. if the input is restricted to .-free graphs, that is, graphs without a fixed graph . as an induced subgraph. We compare our results with a complexity dichotomy for ., the variant where . is part of the input.

On Minimally Non-firm Binary Matricesralised binary matrices and use these operations to derive four infinite classes of minimally non-firm matrices. We hope that our work may pave the way towards a complete characterisation of firm matrices via forbidden submatrices.

New Classes of Facets for Complementarity Knapsack Problemstudies of De Farias et al. for CKP, by proposing three new families of cutting-planes that are all obtained from a combinatorial concept known as a .. Sufficient conditions for these inequalities to be facet-defining, based on the concept of a ., are also provided. Moreover, we answer positively a c

Branch-and-Cut for a 2-Commodity Flow Relocation Model with Time Constraintse model involves an integral flow which represents carriers together with an integral flow which represents the objects transported by those carriers. It may be viewed as the projection on the transit network of a flow model formulated on a time expanded network which simultaneously copes with tempo
