In that applet, we see that a dodecahedron is a volume of space that is bounded by 12 planes. When those planes are extended infinitely, they criss-cross through each other, chopping up space into many …

WebThe path, the wheelbarrow, and the bicycle inequalities have been shown by Cornuéjols, Fonlupt, and Naddef to be facetdefining for the graphical relaxation of STSP(n), the polytope of the symmetric traveling salesman problem on an n-node complete graph. We show that these inequalities, and some generalizations of them, define facets also for STSP(n). In …
