Abstract:
We consider polyhedral cones, associated with quasi-semi-metrics (oriented distances), in particular, with oriented multi-cuts, on n points. We computed the number of facets and of extreme rays, their adjacencies, and incidences of the cones QMETn and OMCUTn for n=3,4,5 (see Table 1) and , partially, for n=6. Some results for general n are also given.
